Totoya to Subaru Oil Fill Funnel Adapter
I have one of those screw-in funnels for my Toyota that makes it harder to make a mess when filling my car with oil - then I got a Subaru, and balked at buying another one (or keeping it - my oil change tote is already overflowing!) - so I just designed an adapter than lets me use my Toyota funnel with my Subaru. Subaru uses M42x4.5 threads, Toyota uses M37x3.0 threads.
Printed on an Enter 3 Pro with tree supports touching the buildplate, 50% infill. The tree supports look knarly but come off surprisingly easily and cleanly.
Here's the type of funnel I have for my Toyota (for info only, no commercial interest in this!): https://www.amazon.com/APSG-Funnel-No-Spill-Directly-Changes/dp/B08YDBV844/ref=sr_1_7?crid=FPM6RD93O9CL&dib=eyJ2IjoiMSJ9._3wf4AGl-VGdY2m1uIiPPtCa5XCOgi0obinPvr7UPJQScPQD0b9Yx8roDLtE5piNuwpvustf0uaT2vaUbldRgOnslLH0aj13Kd2e4bvxnnXiy8HVOVKc7JlLo8q6cWkeW0OohL92_yv8aVR3Fgd7ymOCn3sUUS0MmyfHp7N8c_kBLKvMNVFzoxp6IUbk8rp1i9wt0-oG908r77fkxHyoUEUnqaDm7cKMzEPgvzRpC59zLEfds3ieT6vfdaCwQdULjMuykhPA0BqsZYsdGGtz_yXdnOTaZbXzoGbMfU5XfNXLYiZgimdJ79qjrJ6lub8cOycN9uPv3smapZgNh_IqTkFV5YNXQ72ulHk2gWMHb_ER3Raqas7d-FdO4BrnmJ1JmbnoYzBGDJ6PY4v7BOmGE0pb87TkX9m3F7a9Kdtw9dOs6X4_39lyf0F3Fb95OSf2.P3F-UIQJwtD8MNjV742DBnU_gM3wSAXyosprgfQFJ9o&dib_tag=se&keywords=toyota+oil+fill+funnel&qid=1735484036&sprefix=toyota+oil+fill+funnel%2Caps%2C95&sr=8-7
