Deck Filler with Hose Barb + Winch Cap (Water/Diesel/Waste) — Parametric (3D Print)

🔖 Art. ML3D_0018

🔖 Art. ML3D_0018 Parametric DECK FILLER kit by MarineLab3D — generates TWO parts: the filler body (deck flange + female-threaded through-hull neck ending in an angled HOSE BARB) AND the matching screw cap with a winch-handle socket. You download a ZIP with two separate STL files (filler-body.stl + cap.stl). 🛠️ Through-hull Ø (outer): 40 / 50 / 60 / 75 mm — drives everything ⬇ Flange Ø = through-hull + 26 mm · Cap covers the flange (with O-ring face seal on the cap underside) 🌀 Hose barb Ø is the OUTER diameter and must be ≤ the through-hull Ø 📐 Barb angle adjustable 0–90° 🗝️ Cap opened with a standard winch handle — central 8-point socket (11/16" / 17.5 mm) · countersunk fixing holes 🏷️ Engraved label: WATER / DIESEL / WASTE 🖨️ Print recommendations: for WATER use ASA (best UV resistance) or PETG. For DIESEL or GASOLINE use, print in PA612-CF (10–15% carbon fiber) for fuel resistance. 0.2 mm layers, 3–4 perimeters; print the body with the barb upward or use supports. Fit an O-ring under the cap for sealing. Use “Customize dimensions” to set through-hull Ø, hose barb Ø, barb angle and label, preview in 3D, then receive your ZIP (2 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?
