Bicycle tire lever
I found the radius of the curve on my Park Tool levers too tight so I designed my own lever with a less curvy tip in Fusion 360. I love the curve on my Crank Bros lever but that lever (a great lever for my home wrenching toolbox) was too big to fit in the in-frame tool storage on my gravel bike. The first lever that I printed was in PLA and though it worked OK I decided that PETG was the happy medium of strength and printability. I printed using a Bambu P1S which is enclosed and uses a PEI plate. It stuck well to the bed without a brim. I used cubic infill for more strength.
I have included the Fusion file so you can modify it. Fusion is free for individuals.
