Summary

A printable cup-style oil filter wrench that fits a standard 1/2" ratchet. The inside has 14 flutes to bite the end cap of common spin-on filters. Upload includes several sizes so you can pick the one that matches your filter. Knurled exterior gives extra grip if turning by hand.

 

See https://makerworld.com/en/models/1700791-oil-filter-cup-wrench-3-8-drive-many-sizes-14-cap#profileId-1803645 for my 3/8" drive design. I've added this ½" Inch option (along with stronger print profiles) after some users had issues with strength around the drive with the 3/8" options.

Sizing / How to choose

Make sure you have a 14-flute oil filter (14 is common but some makes use a different number). 

 

Measure the cap end of your oil filter across the flats with calipers. Pick the listed size that is equal to or 0.5–1.0 mm larger than your measurement. If you’re between sizes, choose the larger one. (Example: a 73.2 mm cap → use the 74 mm wrench.)
