Fun little desk car with transmission for both wheels. If you print 2 then the gears all mesh nicely.
I played with radim3D's fidget on my desk for quite a while before thinking what it really needed was another big wheel so it would roll properly. I reduced tolerances quite a bit so things go together easier and roll really smooth.
I used 2 drops of CA glue for each post. I have a fuzzy skin modifier but feel free to disable. No supports easy print.
The author remixed this model.
