Wheel engine thing

Print In Place

Rotate forward and back a few minutes to wear in the gear teeth to free up, add a rubber band as a tire and enjoy!

Diameter: 100mm/4inch
thickness: 12mm/0.5inch
Material weight at 15% infill: 52.57 g/1.85oz

I printed mine with PLA 15% infill 2 layer walls

There are small parts so bed adhesion is critical you might have to print on a raft

Edit: added a model with a tighter tolerance between the body and the ring for people that are better at 3d printing than me

update: Aug 28, 2023, added fusion 360 file (warning its a mess)
