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

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.
