Robot wheel A2
Simple industrial design of a robot wheel. Ideal for small robots.
I designed it for my balancing robot when I realized factory made wheels are too expensive.
Outer diameter: ⌀65mm
Shaft: ⌀4mm (⌀5mm should be also good).
Wall thickness: 3mm
You can stick encoder pattern on the back if you like.
Instructions
Drill hole ⌀4mm or ⌀5mm optionally. (STL hole is ⌀4mm but printer tends to make a bit smaller holes).
Put small M3 nut into square hole.
Screw M3 10 into nut.
Put piece of gum as a tire. In the reference project 20mm wide bicycle inner tube was used.
