XH plugs do not fit PH headers. **How tall is a JST XH header?** About 7 mm above the board for the vertical B-series header; the mated plug adds about 1 mm and the wires exit upward. **Which JST is the 1.25 mm camera and drone connector?** GH (BM-GHS series, with a latch); the non-latching 1.25 mm one many sellers call 'micro JST' is Molex PicoBlade, not JST. ## Fits with - [2.54 mm pin headers, 1×2 to 2×20, vertical and right-angle](https://xemstudio.com/objects/pin-headers-2.54mm/) - [Screw terminal blocks: Phoenix MKDS 1,5 and MKDS 3 (5.0 / 5.08 mm), 2–6 positions](https://xemstudio.com/objects/terminal-blocks/) - [Board connectors: USB Micro-B, Mini-B, RJ45 jack, microSD socket, barrel jacks](https://xemstudio.com/objects/usb-rj45-microsd-connectors/) - [Raspberry Pi Camera Module 3](https://xemstudio.com/objects/raspberry-pi-camera-module-3/) --- # Pluggable terminal block headers: Phoenix MSTBA / MSTBVA 2,5 (5.0 / 5.08 mm), 2–6 positions > What are Phoenix MSTB 2,5 pluggable terminal header dimensions? - Category: Electronics › Connectors - Kind: Standard part - Basis: KiCad 3D models from Phoenix Contact MSTB 2,5 drawings (COMBICON; generic '2EDG' pluggable blocks match) - Page: https://xemstudio.com/objects/pluggable-terminal-blocks/ · JSON: https://xemstudio.com/api/geometry?object=pluggable-terminal-blocks · Plain text: https://xemstudio.com/objects/pluggable-terminal-blocks/sheet.txt - License: dimension sheet CC BY 4.0 (Xem Studio); linked files under their publishers' licenses ## Notes - MSTBA (horizontal) and MSTBVA (vertical) headers accept the MSTB 2,5/..-ST plug; 5.08 mm pitch (5.00 mm metric twin). Header height about 8.6 mm; the plug adds ~16 mm and needs a 12 × (n × 5.08 + 2) mm case opening. - Pin to pin 5.08 mm, pins 1.0 mm diameter; the plug's wire entry is 2.5 mm² max. - Horizontal headers sit at the board edge and the plug extends outward; vertical headers need 25 mm of clearance above the board for the plug and wires. ## Sizes | part | bbox_l_mm | bbox_w_mm | bbox_h_mm | |---|---|---|---| | mstba-2-5-2-g-5-08-1x02-horizontal | 12.6 | 12.2 | 12.0 | | mstba-2-5-2-g-1x02-horizontal | 12.6 | 12.0 | 12.0 | | mstba-2-5-3-g-5-08-1x03-horizontal | 17.2 | 12.6 | 12.0 | | mstba-2-5-3-g-1x03-horizontal | 17.0 | 12.6 | 12.0 | | mstba-2-5-4-g-5-08-1x04-horizontal | 22.3 | 12.6 | 12.0 | | mstba-2-5-4-g-1x04-horizontal | 22.0 | 12.6 | 12.0 | | mstba-2-5-5-g-5-08-1x05-horizontal | 27.4 | 12.6 | 12.0 | | mstba-2-5-5-g-1x05-horizontal | 27.0 | 12.6 | 12.0 | | mstba-2-5-6-g-5-08-1x06-horizontal | 32.5 | 12.6 | 12.0 | | mstba-2-5-6-g-1x06-horizontal | 32.0 | 12.6 | 12.0 | | mstbva-2-5-2-g-5-08-1x02-vertical | 16.0 | 12.2 | 8.6 | | mstbva-2-5-2-g-1x02-vertical | 16.0 | 12.0 | 8.6 | | mstbva-2-5-3-g-5-08-1x03-vertical | 17.2 | 16.0 | 8.6 | | mstbva-2-5-3-g-1x03-vertical | 17.0 | 16.0 | 8.6 | | mstbva-2-5-4-g-5-08-1x04-vertical | 22.3 | 16.0 | 8.6 | | mstbva-2-5-4-g-1x04-vertical | 22.0 | 16.0 | 8.6 | | mstbva-2-5-5-g-5-08-1x05-vertical | 27.4 | 16.0 | 8.6 | | mstbva-2-5-5-g-1x05-vertical | 27.0 | 16.0 | 8.6 | | mstbva-2-5-6-g-5-08-1x06-vertical | 32.5 | 16.0 | 8.6 | | mstbva-2-5-6-g-1x06-vertical | 32.0 | 16.0 | 8.6 | ## Where the files are - KiCad: [kicad-packages3D library (origin of these files)](https://gitlab.com/kicad/libraries/kicad-packages3D) — STEP, WRL — CC BY-SA 4.0 with KiCad exception ## Free STEP/STL (20 parts, CC BY-SA 4.0 (KiCad library license, with the KiCad exception), KiCad library contributors) Index: https://xemstudio.com/files/kicad/pluggable-terminal-blocks/index.json · license: https://xemstudio.com/files/kicad/pluggable-terminal-blocks/LICENSE.md - mstba-2-5-2-g-5-08-1x02-horizontal: [STEP](https://xemstudio.com/files/kicad/pluggable-terminal-blocks/mstba-2-5-2-g-5-08-1x02-horizontal.step) · [STL](https://xemstudio.com/files/kicad/pluggable-terminal-blocks/mstba-2-5-2-g-5-08-1x02-horizontal.stl) — KiCad Connector_Phoenix_MSTB: PhoenixContact_MSTBA_2,5_2-G-5,08_1x02_P5.08mm_Horizontal;

Fittings grip the OD; a printed adapter that slips over the pipe uses OD + 0.3 mm. - Type L (blue) wall: 1/2 1.02, 3/4 1.14, 1 1.27 mm. Type M (red) is thinner: 0.71, 0.81, 0.89 mm. Type K (green) is thicker still and rarer. - Why it's here: copper's conductivity makes 3/4 and 1 in Type L tube the hot and cold heat-exchanger walls on the LES Stirling heads; 1/4 and 3/8 are regenerator and transfer tubes. ## Sizes | nominal_in | od_mm | type_l_wall_mm | type_l_id_mm | type_m_wall_mm | type_m_id_mm | |---|---|---|---|---|---| | 1/4 | 9.53 | 0.76 | 8.01 | 0.64 | 8.25 | | 3/8 | 12.7 | 0.89 | 10.92 | 0.64 | 11.42 | | 1/2 | 15.88 | 1.02 | 13.84 | 0.71 | 14.46 | | 3/4 | 22.22 | 1.14 | 19.94 | 0.81 | 20.6 | | 1 | 28.58 | 1.27 | 26.04 | 0.89 | 26.8 | | 1-1/4 | 34.93 | 1.65 | 31.63 | 1.07 | 32.79 | | 1-1/2 | 41.28 | 1.52 | 38.24 | 1.24 | 38.8 | | 2 | 53.98 | 1.78 | 50.42 | 1.47 | 51.04 | ## Where the files are - Wikipedia: [Copper tubing](https://en.wikipedia.org/wiki/Copper_tubing) — web — CC BY-SA 4.0 (text) - Copper Development Association: [Copper Tube Handbook (dimensions table)](https://www.copper.org/publications/pub_list/pdf/copper_tube_handbook.pdf) — PDF — CDA publication (verify at link) - Long Earth Society: [Engine builds that use these parts (videos and write-ups)](https://longearthsociety.com/engineering/) — web, video — LES site ## Free STEP/STL (8 parts, CC BY 4.0, Xem Studio) Index: https://xemstudio.com/files/hardware/copper-pipe-type-l-m/index.json - copper-1-4in-typeL-50mm: [STEP](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-1-4in-typeL-50mm.step) · [STL](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-1-4in-typeL-50mm.stl) — 1/4 in nominal, OD 9.53 mm, Type L wall 0.76 mm, 50 mm stub - copper-3-8in-typeL-50mm: [STEP](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-3-8in-typeL-50mm.step) · [STL](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-3-8in-typeL-50mm.stl) — 3/8 in nominal, OD 12.7 mm, Type L wall 0.89 mm, 50 mm stub - copper-1-2in-typeL-50mm: [STEP](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-1-2in-typeL-50mm.step) · [STL](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-1-2in-typeL-50mm.stl) — 1/2 in nominal, OD 15.88 mm, Type L wall 1.02 mm, 50 mm stub - copper-3-4in-typeL-50mm: [STEP](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-3-4in-typeL-50mm.step) · [STL](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-3-4in-typeL-50mm.stl) — 3/4 in nominal, OD 22.22 mm, Type L wall 1.14 mm, 50 mm stub - copper-1in-typeL-50mm: [STEP](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-1in-typeL-50mm.step) · [STL](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-1in-typeL-50mm.stl) — 1 in nominal, OD 28.58 mm, Type L wall 1.27 mm, 50 mm stub - copper-1-1-4in-typeL-50mm: [STEP](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-1-1-4in-typeL-50mm.step) · [STL](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-1-1-4in-typeL-50mm.stl) — 1-1/4 in nominal, OD 34.93 mm, Type L wall 1.65 mm, 50 mm stub - copper-1-1-2in-typeL-50mm: [STEP](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-1-1-2in-typeL-50mm.step) · [STL](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-1-1-2in-typeL-50mm.stl) — 1-1/2 in nominal, OD 41.28 mm, Type L wall 1.52 mm, 50 mm stub - copper-2in-typeL-50mm: [STEP](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-2in-typeL-50mm.step) · [STL](https://xemstudio.com/files/hardware/copper-pipe-type-l-m/copper-2in-typeL-50mm.stl) — 2 in nominal, OD 53.98 mm, Type L wall 1.78 mm, 50 mm stub ## Questions **What is the OD of 3/4 inch copper pipe?** 22.22 mm (0.875 in). 1/2 in is 15.88 mm, 1 in is 28.58 mm: always nominal + 1/8 in. **What is the difference between Type L and Type M copper?** Wall thickness only: 1/2 in Type L is 1.02 mm, Type M 0.71 mm; same OD, same fittings. **What size hole for 1/2 inch copper pipe to pass through?** 16.2 mm (OD 15.88 + 0.3) for a slip fit; 16.5 mm if the pipe is painted or the print is rough. ## Fits with - [Schedule 40 pipe and PVC fittings, 1/2 to 2 inch](https://xemstudio.com/objects/schedule-40-pipe/) - [Tri-clamp (Tri-Clover) sanitary ferrule, 1/2 to 4 inch](https://xemstudio.com/objects/tri-clamp-ferrule/) - [Hobby brass tube (K&S), 1/16–21/32 in and 1–12 mm, telescoping](https://xemstudio.com/objects/brass-tube-ks/) - [O-rings, common metric sizes (ISO 3601)](https://xemstudio.com/objects/o-rings-metric/) - [Pipe thread envelopes: NPT (ANSI B1.20.1) and BSP (ISO 228 / 7), 1/8 to 1 inch](https://xemstudio.com/objects/npt-bsp-thread-envelopes/) --- # Crank discs, connecting rods and flywheels for model engines > What stroke and flywheel size does a small Stirling engine need?

Tooth depth 3 mm prints cleanly. **Which way does the pawl point?** Its contact point trails the pivot in the locking direction so load drives it into the tooth; the back of the tooth lifts it on the free stroke. **Can a printed ratchet hold an engine flywheel?** Yes at model scale: a 12-tooth PETG wheel with a 6 mm face holds several N·m; keep the pawl thick (6 mm) and pivot it on a 3 mm steel pin. ## Fits with - [Spur gears, involute 20°: module 0.5, 1 and 2, 12–60 teeth](https://xemstudio.com/objects/spur-gears-involute/) - [Crank discs, connecting rods and flywheels for model engines](https://xemstudio.com/objects/crank-conrod-flywheel-kit/) - [Dowel pins, 2–6 mm (ISO 2338 / DIN 6325)](https://xemstudio.com/objects/dowel-pins-metric/) - [Ball bearings, 683 to 6210 and flanged F6xx (ISO 15)](https://xemstudio.com/objects/ball-bearings-metric/) --- # Spur gears, involute 20°: module 0.5, 1 and 2, 12–60 teeth > What is the outer diameter and centre distance for module 1 spur gears? - Category: Hardware › Stirling & thermoacoustic - Kind: Hardware - Basis: ISO 53 / DIN 867 basic rack, 20° pressure angle, standard addendum (1 m) and dedendum (1.25 m); true involute flanks generated point by point - Page: https://xemstudio.com/objects/spur-gears-involute/ · JSON: https://xemstudio.com/api/geometry?object=spur-gears-involute · Plain text: https://xemstudio.com/objects/spur-gears-involute/sheet.txt - License: dimension sheet CC BY 4.0 (Xem Studio); linked files under their publishers' licenses ## Notes - Pitch diameter = module × teeth; outer diameter = module × (teeth + 2); centre distance between two gears = module × (N1 + N2) / 2.

Two module-1 gears with 20 and 40 teeth sit 30 mm apart; add 0.1–0.15 mm for printed backlash. **What is the smallest gear module that 3D prints well?** Module 1 with a 0.4 mm nozzle (tooth thickness 1.57 mm at the pitch line); module 0.8 is marginal; module 0.5 needs resin or a 0.2 mm nozzle. **What pressure angle are these gears?** 20°, the modern standard; they mesh with any 20° involute gear of the same module, including brass stock gears. ## Fits with - [Crank discs, connecting rods and flywheels for model engines](https://xemstudio.com/objects/crank-conrod-flywheel-kit/) - [Ratchet wheels and pawl (anti-reverse / one-way drive)](https://xemstudio.com/objects/ratchet-and-pawl/) - [Ball bearings, 683 to 6210 and flanged F6xx (ISO 15)](https://xemstudio.com/objects/ball-bearings-metric/) - [Dowel pins, 2–6 mm (ISO 2338 / DIN 6325)](https://xemstudio.com/objects/dowel-pins-metric/) - [Set screws (grub screws), M3–M8 (ISO 4026)](https://xemstudio.com/objects/set-screws-metric/) - [NEMA 17 stepper motor](https://xemstudio.com/objects/nema-17-stepper/) --- # Thermoelectric (Peltier) modules: TEC1-12706, 12710, 30 mm > What are TEC1-12706 dimensions? - Category: Hardware › Stirling & thermoacoustic - Kind: Hardware - Basis: Common TEC1 module sizes from manufacturer datasheets (Hebei I.T., Laird equivalents); thickness varies ±0.1 mm by maker - Page: https://xemstudio.com/objects/thermoelectric-tec1/ · JSON: https://xemstudio.com/api/geometry?object=thermoelectric-tec1 · Plain text: https://xemstudio.com/objects/thermoelectric-tec1/sheet.txt - License: dimension sheet CC BY 4.0 (Xem Studio); linked files under their publishers' licenses ## Notes - TEC1-12706: 40 × 40 × 3.8 mm (127 couples, 6 A, ~60 W heat pumping at ΔT 0); the standard hobby module. TEC1-12710: 40 × 40 × 3.3–3.4 mm, 10 A. 30 × 30 × 3.4 mm modules (TEC1-12704, 03104 class) for small loads. 50 × 50 and 62 × 62 exist for high current. - Leads exit one edge (red +, black −); keep 5 mm clear there. Hot and cold faces are the ceramic plates: clamp between heat sinks with thermal paste, 4 × M3 at the heat-sink corners, never over-tighten (ceramic cracks). - As a generator (Seebeck) a 12706 gives ~1–2 W at ΔT 100 K; the high-temperature TEG modules (TEG1-12611 etc.) share the 40 × 40 footprint but run to 300 °C. - Why it's here: the LES thermoacoustic builds use a 12706 as a ΔT instrument and as a TEG on the cold spool to run the fan. ## Sizes | module | size_mm | thickness_mm | i_max_a | note | |---|---|---|---|---| | TEC1-12706 | 40 × 40 | 3.8 | 6 | standard hobby module | | TEC1-12710 | 40 × 40 | 3.4 | 10 | thinner | | TEC1-12704 / 03104 | 30 × 30 | 3.4 | 4 | small | | TEC1-12730 | 62 × 62 | 4.8 | 30 | large | ## Where the files are - Wikipedia: [Thermoelectric cooling](https://en.wikipedia.org/wiki/Thermoelectric_cooling) — web — CC BY-SA 4.0 (text) - Hebei I.T.

Fits between any two 40 mm heat sinks. **What is the difference between TEC1-12706 and 12710?** Current rating (6 vs 10 A) and thickness: 3.8 vs 3.3–3.4 mm. Same 40 × 40 footprint. **Can a Peltier module generate power?** Yes, as a Seebeck generator: a 12706 gives roughly 1–2 W at a 100 K temperature difference, enough for a 40 mm fan; dedicated TEG modules tolerate higher temperatures. ## Fits with - [120 mm axial fan](https://xemstudio.com/objects/120mm-fan/) - [Axial fans, 25 to 140 mm: frames and hole patterns](https://xemstudio.com/objects/axial-fan-frames/) - [Socket head cap screws, M2–M8 (ISO 4762 / DIN 912)](https://xemstudio.com/objects/socket-head-cap-screws-metric/) - [Tri-clamp spool (two ferrules on a tube), 1.5 and 2 inch](https://xemstudio.com/objects/tri-clamp-spool/) - [Copper pipe (ASTM B88 Type L and M), 1/4 to 2 inch](https://xemstudio.com/objects/copper-pipe-type-l-m/) --- # Tri-clamp (Tri-Clover) sanitary ferrule, 1/2 to 4 inch > What are tri-clamp ferrule dimensions: flange OD, tube OD and which sizes share a clamp? - Category: Hardware › Tri-clamp - Kind: Hardware - Basis: ISO 2852:1974 face profile (rim 2.85, recess 1.6, 20° back angle, groove diameters) with ASME BPE tube sizes; 16 ga wall - Page: https://xemstudio.com/objects/tri-clamp-ferrule/ · JSON: https://xemstudio.com/api/geometry?object=tri-clamp-ferrule · Plain text: https://xemstudio.com/objects/tri-clamp-ferrule/sheet.txt - License: dimension sheet CC BY 4.0 (Xem Studio); linked files under their publishers' licenses ## Notes - Clamp size follows the flange OD, not the tube: 1/2 and 3/4 in share a 25.4 mm flange; 1 and 1.5 in share 50.5 mm; 2 in is 64.0; 2.5 in 77.5; 3 in 91.0; 4 in 119.0 mm. - Face (ISO 2852 §6.1): a flat sealing land from the groove diameter C2 out to the rim, and a recess 1.6 mm deep (K) from C2 in to the bore, where the gasket bead sits. C2 = 43.5 mm for the 50.5 flange, 56.5 for 64.0, 83.5 for 91.0. Radii R2 2.0 / R3 1.2 mm. - Rim thickness L1 = 2.85 mm; the back of the flange is a 20° cone (α) rising to the hub, which is what the clamp's V-ring grips. Hub thickness works out to about 5.3 mm on a 2 in weld ferrule. - Weld ferrules: 21.5 mm (ISO/short) or 28.6 mm (ASME BPE medium); 44.5 / 57.2 mm long versions exist. Tube end plain for a butt weld. - Printing it: this profile prints true in PLA/PETG for mock-ups and clamp fit checks; the sealing land needs a smooth top layer. Real parts are 304/316 stainless. - Why it matters here: a thermoacoustic/Stirling engine body built from 2 in tri-clamp parts is a stack of ferrules, spools and caps; print the stack first, then buy steel. ## Sizes | nominal_in | tube_od_mm | tube_od_in | wall_mm | flange_od_mm | groove_dia_mm | clamp_size | |---|---|---|---|---|---|---| | 1/2 | 12.7 | 0.5 | 1.65 | 25.4 | n/a in ISO sample | 1/2–3/4 | | 3/4 | 19.05 | 0.75 | 1.65 | 25.4 | n/a in ISO sample | 1/2–3/4 | | 1 | 25.4 | 1.0 | 1.65 | 50.5 | 43.5 | 1–1.5 | | 1-1/2 | 38.1 | 1.5 | 1.65 | 50.5 | 43.5 | 1–1.5 | | 2 | 50.8 | 2.0 | 1.65 | 64.0 | 56.5 | 2 | | 2-1/2 | 63.5 | 2.5 | 1.65 | 77.5 | n/a in ISO sample | 2.5 | | 3 | 76.2 | 3.0 | 1.65 | 91.0 | 83.5 | 3 | | 4 | 101.6 | 4.0 | 2.11 | 119.0 | n/a in ISO sample | 4 | ## Where the files are - ISO (via iTeh sample): [ISO 2852:1974 clamp liners with gaskets (face and gasket profile, §6.1 and §8)](https://cdn.standards.iteh.ai/samples/7850/eb49c396488d408c8ced3e2961d76cf3/ISO-2852-1974.pdf) — PDF — standard excerpt; dimensions are facts - McMaster-Carr: [Sanitary (quick-clamp) tube fittings (free STEP per part, for your own design use; no redistribution)](https://www.mcmaster.com/products/sanitary-fittings/) — STEP, PDF — McMaster-Carr site terms: personal design use, no redistribution (verify at link) - Dixon Valve: [Sanitary fittings catalog (dimensions)](https://www.dixonvalve.com/en/sanitary-fittings) — PDF — vendor catalog (verify at link) - Wikipedia: [Tri-clamp fitting](https://en.wikipedia.org/wiki/Tri-clamp) — web — CC BY-SA 4.0 (text) (verify at link) - Long Earth Society: [The engine built from tri-clamp parts](https://longearthsociety.com/engineering/custom-high-temp-stirling/) — web — CC BY 4.0 (text) ## Free STEP/STL (8 parts, CC BY 4.0, Xem Studio) Index: https://xemstudio.com/files/hardware/tri-clamp-ferrule/index.json - tc-ferrule-1in-21.5mm: [STEP](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-1in-21.5mm.step) · [STL](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-1in-21.5mm.stl) — 1 in weld ferrule, 21.5 mm, 16 ga; ISO 2852 face (2.85 rim, 1.6 recess, 20° back) - tc-ferrule-1in-28.6mm: [STEP](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-1in-28.6mm.step) · [STL](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-1in-28.6mm.stl) — 1 in weld ferrule, 28.6 mm, 16 ga; ISO 2852 face (2.85 rim, 1.6 recess, 20° back) - tc-ferrule-1.5in-21.5mm: [STEP](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-1.5in-21.5mm.step) · [STL](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-1.5in-21.5mm.stl) — 1.5 in weld ferrule, 21.5 mm, 16 ga; ISO 2852 face (2.85 rim, 1.6 recess, 20° back) - tc-ferrule-1.5in-28.6mm: [STEP](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-1.5in-28.6mm.step) · [STL](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-1.5in-28.6mm.stl) — 1.5 in weld ferrule, 28.6 mm, 16 ga; ISO 2852 face (2.85 rim, 1.6 recess, 20° back) - tc-ferrule-2in-21.5mm: [STEP](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-2in-21.5mm.step) · [STL](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-2in-21.5mm.stl) — 2 in weld ferrule, 21.5 mm, 16 ga; ISO 2852 face (2.85 rim, 1.6 recess, 20° back) - tc-ferrule-2in-28.6mm: [STEP](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-2in-28.6mm.step) · [STL](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-2in-28.6mm.stl) — 2 in weld ferrule, 28.6 mm, 16 ga; ISO 2852 face (2.85 rim, 1.6 recess, 20° back) - tc-ferrule-3in-21.5mm: [STEP](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-3in-21.5mm.step) · [STL](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-3in-21.5mm.stl) — 3 in weld ferrule, 21.5 mm, 16 ga; ISO 2852 face (2.85 rim, 1.6 recess, 20° back) - tc-ferrule-3in-28.6mm: [STEP](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-3in-28.6mm.step) · [STL](https://xemstudio.com/files/hardware/tri-clamp-ferrule/tc-ferrule-3in-28.6mm.stl) — 3 in weld ferrule, 28.6 mm, 16 ga; ISO 2852 face (2.85 rim, 1.6 recess, 20° back) ## Questions **What is the flange OD of a 2 inch tri clamp ferrule?** 64.0 mm. 1 in and 1.5 in share a 50.5 mm flange and the same clamp; 2.5 in is 77.5 mm; 3 in is 91.0 mm; 4 in is 119.0 mm. **Are 1 inch and 1.5 inch tri clamp fittings interchangeable?** The flanges are the same (50.5 mm OD, 43.5 mm groove) so a 1.5 in clamp and gasket fit both; the tube bores differ (25.4 vs 38.1 mm OD tube). **What are the ISO 2852 tri clamp face dimensions?** Rim thickness 2.85 mm, gasket recess 1.6 mm deep inside the groove diameter (43.5 / 56.5 / 83.5 mm for 50.5 / 64 / 91 flanges), 20° back cone that the clamp grips. The free STEP files here use exactly that profile. **Can I 3D print a tri clamp ferrule?** For mock-ups, fit checks and low-pressure air, yes: the STEP/STL here follow the ISO 2852 face so a real clamp and gasket seat on them.
