This is for all you makers that don't have a 24mm socket handy to change the oil in your Pentastar Jeep. A box end wrench or large crescent will work if you don't mind going 1/16 turn at a time against the drag of your old o-ring, but this makes it a little easier.
1/2" drive tested in PLA and was able to torque filter housing to spec (25 N·m /18 ft. lbs.) as well as break it free initially without breaking the socket. In destructive testing the PLA version failed at 28 ft. lbs. You may want a large crescent to "start" your cover depending on how long it's been since it was last removed.
Thicker (stronger) version with combo drive for 3/8" or 1/2". This will be stronger at the cost of a longer print time and more material used. Destructive testing will be done shortly and results posted... RE-UPLOADED w/ fixed scaling - Thanks for the feedback :-)
I printed this with a shell thickness of 4mm instead of the usual 1.6mm. This gives a "solid" part which tested as the strongest versus a 100% infill on a thinner shell. This may be entirely due to other print settings, or quirks of my particular printer. I'd love feedback from makers trying different methods and materials.
