Printable tri-clamp (45°): tees, short-outlet tees and crosses, ½ to 4 in — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/printable-tri-clamp-tees-crosses/ (CC BY 4.0) Basis: Xem Studio design: standard 7MP / 7MPS / 9MP layout per size, 45° rims Catalog version: 2026-10-20 Sizes: see table below - Print with the run vertical and one run face down. - Printable tri-clamp: the ISO 2852 face and gasket groove are exactly standard, only the back cone behind each rim is 45° instead of 20°, so no rim overhangs more than 45° from vertical in any print orientation. Join these with the 45° clamps (printable-tri-clamp-clamps) and standard Type B gaskets; a 45° clamp fits only 45° rims, so keep a run all 45°. A 45° cone turns clamp force into face force at 1 : 1 (a 20° cone at 2.7 : 1), so tighten the clamp bolts harder or use M6. - Print orientation: straight parts face down; elbows, tees and crosses with one face down; horizontal bores bridge their top, so keep them small or add a light tree support inside. - Every clamp face is the ISO 2852 profile used across this site: 2.85 mm rim, flat face with the gasket groove (K 1.6 deep, R3 1.2 bottom, 23° walls, P2 0.8 edges) on C2, 20° back cone.
