Post-Printing

I don't like supports, therefore the wheel has a domed recess for the bearing. Depending on your settings, you may need to scale up/down a bit (the bearing should be tight both on the part and the axle)

How I Designed This

I noticed that the wheels did not turn as freely as I wanted and that the shaft is 10mm in diameter (i also had some 6700ZZ bearings handy from another project), therefore i modified the source file to accept the bearing.
