Summary

A printable cup-style oil filter wrench that fits a standard 3/8" 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.

A stronger ½" Inch Drive Version is available here if preferred: https://makerworld.com/en/models/1815200-oil-filter-cup-wrench-1-2-drive-many-sizes-14-cap#profileId-1936957

63.5	Select Honda (Civic, Accord) spin-on filters; some older Toyota Corolla
64	Toyota, Lexus, Scion (most 4-cyl. & V6 engines with cartridge filters); some BMW motorcycles
65	Many GM vehicles (Chevrolet Cruze, Equinox) with PF-xxx series filters

Features

3/8" square drive (female) in the base
14-flute profile works with many OEM and aftermarket filters
Tapered load cone to keep force centered on the drive
Knurled outer ring for hand-tightening/loosening before using a ratchet
Thick walls and generous fillets for strength
No Supports Required (Min. Bridge Angle 45°)

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.)

Any Support is Appreciated!

I printed this to try and help get a VERY stubborn oil filter off, I printed it in petg and it fit perfectly snug over the filter, but the 3/8 ratchet drive stripped out that hole. I wonder if that geometry could be strengthened? Will add a picture later

@3LittleBirds3D

Helpful feedback! Easy thing to try would be up up wall layers to 6 & infill to 25% or more. But this has got me thinking perhaps I should also change the design to a 1/2” drive to give it the best chance of survival. I must admit I didn’t have a very stubborn filter to try the design on. Thank you.

Replying to @3LittleBirds3D :

@GWInnovations That's a great idea for solving, the additional contact area of the 1/2" should keep it much more secure, maybe you can add that and a "high-strength" print profile with extra walls? The design itself worked great, the filter was just almost impossible to remove, it felt like someone must have used an impact wrench to secure it on! So not a problem with your design at all.

I've just posted a stronger print profile. When I get a little time I'm going to design that 1/2" Drive version as well.

@user_1496230772

No 64mm 14 flute on the files. Would appreciated if you add the numbers to the models. Thanks

The designer has replied

@3LittleBirds3D

Added 64mm stl file - good catch... will look at building number into models. Thank you.

@3LittleBirds3D

Added sizes as deboss on each option now. Thanks for the suggestion.

Why didn't I think of looking for this part sooner 😅 I just printed the part in PETG, in the right size it was finished in 1.5 hours and fits perfectly 👌🏽 very good work 👏🏾 I used it for a Honda CBR in 65mm

Strength Issue:I also had issues with my ratchet stripping the hole. Printed in PLA. Ended up screwing the print to a block of wood for leverage and managed to get my oil filter out.

Great print but did not work for me. I printed the 65mm version according to the chart in the description, but after actually measuring and looking at one of the many PF filters we have it would not work. The PF series filters have 15 flutes on them and are 73mm/74mm (i believe) in diameter.

solid print, no issues at all.

Strength Issue:Tried in PLA and PETG. A more durable material might have improved my results, but both versions of the tool gave out and broke when I tried to used them on my filter. If the service mechanics actually hand tightened the filter instead of torquing it to oblivion it probably would have worked fine

The profile uploader has replied

@3LittleBirds3D

Doh. I recommend the 1/2” drive version for more strength. You could also go to 100% infill if you want to take it to another level. Sounds like a very over tightened filter but regardless I don’t want it to break on you - sorry. https://makerworld.com/en/models/1815200-oil-filter-cup-wrench-1-2-drive-many-sizes-14-cap#profileId-1936957

Sorry to hear that. How did it fail?

@3LittleBirds3D

Replying to @3LittleBirds3D :

I’ve uploaded a stronger print profile and also a 1/2” drive design which should be considerably stronger. Thanks for your feedback. https://makerworld.com/en/models/1815200-oil-filter-cup-wrench-1-2-drive-many-sizes-14-cap#profileId-1936957

Strength Issue:The model broke immediately - poor hole design, stiffeners need to be added

The profile uploader has replied

@3LittleBirds3D

Hmmm… sorry to hear that. It’s already strengthened around the drive. You could try the 1/2” drive variant which will be stronger. Sounds like stubborn filter.
