Drain tube adapter for Fumoto valve

Update 2021/07/19: Added a plug to cap the Fumoto valve to keep out dirt/mud/snow. Make sure print this (and the coupling) in the original orientation with the smaller diameter against the build plate/bed, otherwise there will be overhangs that won't print correctly and it probably won't fit well.

I designed this adapter to fit the Fumoto F133S engine oil drain valve, but it should fit any of the Fumoto large body drain valves with the short nipple (11mm x 5.3mm). The coupling (red part) was printed in TPU so it can snap on securely and off easily. The angled adapter allows me to rotate it to aim the oil stream into the drain pan rather than having it hit the front wheel and/or suspension. The barbed end will allow you to connect a length of 5/8" ID (~16mm) hose to drain around skid plates, crossmembers, etc, if needed.

TPU and PETG aren't suitable materials to be left in place indefinitely, so remove after the oil change is complete.

Update 2022/02/03: I've used this a few times now and it's worked great to drain the oil directly into a couple gallon jugs.  The PETG and TPU has held up well to the oil. I figured it would breakdown in some way (get brittle or soften) but they have held up well.

100%, 20%

Filament: YOYI 85A TPU Red, Duramic PETG Silver

Notes:

Print the coupling in TPU with 8 walls/perimeters so it's totally solid at 0.2 layer height without supports. I used YOYI 85A TPU as that's what I had on hand.

Print the angled adapter in PETG or PLA+ with 3 walls, 6 top and bottom layers, 20% infill at 0.16 layer height. The adapter will need a brim to keep it from coming loose from the bed while printing.
