Elbow — BSP Male × Hose Barb — Parametric (3D Print)

🔖 Art. ML3D_0013 Parametric elbow fitting — male BSP thread on one side, hose barb on the other — by MarineLab3D. Choose the bend angle and both sizes. For 3D printing in PETG or PA12. 📐 Bend angle: 45° to 160° 🔧 Male BSP thread: 1/8" to 2 1/2" (BSPP parallel, DIN hex sizing reference) 🪝 Hose inner diameter: 6 to 60 mm 🔩 BSPP thread seals with O-ring / PTFE; barbed tail sized to the hose ID 🖨️ Print recommendations: print with supports (the elbow has overhangs). PETG or PA12, 0.15–0.2 mm layers, 3 perimeters. Use “Customize dimensions” to set angle + thread + hose, preview in 3D, then receive your STL after purchase. ⚠️ 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. Most 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. Only for pressures above ~4 bar: also brush a thin coat of epoxy resin inside for a guaranteed seal. A 3D-printed fitting is a valid solution but always verify it for your specific application. 🖨️ No 3D printer?
