From-scratch build for wheel steering (hardware)

[seandepagnier]

start by printing the largest htd5m toothed pulley you can that will mount on a wheel. with 300x300mm you should be able to print at least a 140 tooth pulley in a single piece.

Also a smaller one for the motor around 20-30 tooth, or just buy a metal one they are cheap enough at this size. i have stl and scad files if you want.
