Hydroponic tower, printable tri-clamp (4 in, gasketed, no supports) — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/hydroponic-tower-tri-clamp/ (sheet CC BY 4.0) Basis: Xem Studio design: geometry computed in tools/gen_hydro.py; ISO 2852 faces with the 45° printable back cone; snap clamp per tools/gen_tc_snap.py Catalog version: 2026-10-20 Overall (mm): length 209.6, width 190.3, height 441.4 - A vertical hydroponic tower that stacks like sanitary pipe: 4 in printable tri-clamp faces, a silicone gasket and Xem's bolt-free snap clamp at every joint, so the column does not leak at its joints and comes apart for cleaning. Lighting is external (grow light or window). - Planting level: three 2 in printable tri-clamp cuffs at 45° blended into the column (R4), 152 mm face to face (154 mm per level with the gasket). Each level's rain floor is printed flush with its bottom face: 243 Ø2.5 rain holes, 59 wall drains next to the bore, a 5 mm dam and a snap clip that centres the pump hose. - Pots are 2 in tri-clamp ferrules themselves: a slotted body (Ø44 → Ø36, 80 mm, or 40 mm for seedlings) slides down the cuff and the pot's face clamps onto the cuff's face with a 2 in gasket and a 2 in snap clamp, so it seals and cannot be knocked out. An unused position takes a 2 in cap. - 2 in clamps on the 45° cuffs: cuff face 91.8 mm from the column axis; the closed clamp (Ø82) stays 4.5 mm off the column and 77.0 mm from the next cuff's clamp, and clears the 4 in clamps above and below. - Quiet water path: the hose ends in a standpipe under the lid whose side windows spill into a stream-breaker ring (≤ 7.4 mm drop), out at floor level onto the rain floor; the water rains on the roots and runs down the wall; it returns through a funnel whose down-pipe ends under the water line. - Two bases: a 5 gal bucket (threaded through-lid adapter with two 2 in port cuffs, spigot and return funnel) or a printed Ø246 × 250 mm countertop tank with a 4 in neck and two 2 in cuffs on the shoulder. A port takes the pump cord under the slotted 2 in cap (the cap still clips on), a probe, or a refill; the plain cap closes it. - Every part fits a 256 mm cube and prints without supports in its file's orientation, checked layer by layer (each 0.2 mm layer on the one below grown 45°): the only flat ceilings are bridges ≤ 4.5 mm, and under each 45°-tilted 2 in cuff rim the clamp's 45° bearing cone turns horizontal at its lowest point (a crescent ledge ≤ 4.5 mm, printed with the fan on). Watertight STLs; assembled with gaskets and clamps without interference. A clamp key (lever) opens the snap clamps. - Assembled with a bucket base and two levels: lid top 441.4 mm above the bucket lid. - The STEP/STL pack (all parts, an assembled STEP, README with print settings, assembly order and what to buy) is $15 by card, or $12 for AI agents paying with x402 at /api/buy/hydroponic-tower-kit. The dimension sheet here is free. - The download is the envelope at the published size: true size, no printing allowance.
