ML3D_0011\nParametric 3-way T hose barb connector — barb on all three ports — by MarineLab3D.\nTwo in-line barbs plus a perpendicular branch, on a cylindrical central body sized to the largest port.\nFor 3D printing in PETG or PA12.\n\n🪝 Hose A \/ B \/ C inner diameter: 6 to 60 mm (each port independent)\n⬡ Central cylindrical body auto-sized to the largest hose\n↔ Internal T passage joining all three ports\n🔩 Barbed tails (3–4 ridges) sized to the hose inner diameter\n\n🖨️ Print recommendations: print with supports (the T shape has overhangs whatever the orientation). PETG or PA12, 0.15–0.2 mm layers, 3 perimeters. Secure hoses with clamps.\n\nUse “Customize dimensions” to set the three hose sizes, preview in 3D, then receive your STL after purchase.\n\n⚠️ PRESSURE USE (above ~1 bar): print in PETG (not ASA — better layer sealing), with SOLID walls (enough perimeters to fully fill the wall thickness — do not rely on infill), Z-seam set to “Scarf joint”, low part-cooling fan, flow +2–3%, and the thread\/seam axis VERTICAL.\nMost onboard plumbing systems run at max ~3 bar: at this level these print settings + a GENEROUS amount of PTFE tape \/ thread sealant on the threads are enough. Always pressure-test at ~2× working pressure before use.\nOnly for pressures above ~4 bar: also brush a thin coat of epoxy resin inside for a guaranteed seal.\nA 3D-printed fitting is a valid solution but always verify it for your specific application.\n\n🖨️ No 3D printer?

PETG\/TPE also possible for rigid spacers.\n\n⚠️ Note: a 3D-printed O-ring does not match the mechanical properties of an industrial moulded one, but it is a valid TEMPORARY \/ emergency alternative when you can’t get the original part.\n\nUse “Customize dimensions” to set profile, sizes and inner Ø, preview in 3D, then download free.\n\n🖨️ No 3D printer?
