Double Tires for N20 Motors (or anything with a 3mm D-Shaft)

A copy of the ever present 34mm x 7mm wheels you can find all over amazon, ebay, aliexpress, etc. but with double the tires ;) The rubber tires themselfs are from those 34mm x 7mm wheels.

Should fit the 3mm D-shaft of any N10/N20/N30 motor.

I included the step file, if someone needs to adjust the D-shaft tolerances or something.

Print settings:

- high number of perimeters - 100% infill - organic supports, to get some clean overhangs. Probably works good with regular supports too. - Almost no post processing needed, remove the support and use a reemer or knife for the shaft hole edges for easier insertion of the D-shaft
