Interesting idea, the author 3D printed out the holder for the “wheel” from a roller from a Xerox machine. The rubber rollers are pretty durable and the rubber part will help with not slipping of the wheel. Not so sure how much weight the 3D printed part and screw can support thought. Could be a good build for small robots.
