I modified the Wheel Drive to 1mm O-rings that I already had here.
I increased the hole of them a little for my printer, (3.05mm) and the fit in the carbon axles was a little easier, but they were strong. Worked perfectly.
I took advantage of the fact that I also had the 12mm N20 mini motors and I already made the motor mount for it, although I already have the ercintorun remix: https://www.thingiverse.com/thing:4360572
I preferred a simpler design that worked well too.
The motor must fit very tightly, and the cage of the mini gears should be touching the plastic.
Prefer motor with 7.2mm shaft that fits perfectly.
It is also possible to use the 9/10mm axis, just by placing the motor mount inverted.
The 300 to 500 rpm is ideal.
O-rings are 15x1mm
Enjoy
