Printable tri-clamp (45°): reducing tees, ¾ to 4 in run
Can I 3D print a tri-clamp reducing tee? · Hardware · basis: Xem Studio design: S7RMP layout per run × branch, 45° rims
Exact dimensions. True size, with no printing tolerance added.

Notes
- Same layout as the standard reducing tees.
- 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. Flange C3 / groove C2 / tube OD × wall, mm: ½–¾ in 25.0 / 20.4 (derived) / 12.7–19.05 × 1.65; 1–1½ in 50.5 / 43.5 / 25.4–38.1 × 1.65; 2 in 64.0 / 56.5 / 50.8 × 1.65; 2½ in 77.5 / 70.5 / 63.5 × 1.65; 3 in 91.0 / 83.5 / 76.2 × 1.65; 4 in 119.0 / 110.0 / 101.6 × 2.11; 6 in 166.9 (6.570 in) / 156.5 / 152.4 × 2.77; 8 in 217.7 (8.570 in) / 207.0 / 203.2 × 2.77; 10 in 268.5 / 261.0 / 254.0 × 3.40; 12 in 319.3 / 311.8 / 304.8 × 3.40.
