Tools

  • A 3D printer.
  • A drill with roughly a 3mm bit.

Ingredients

  • Some 3mm-ish metal rod. I used an old coathanger.
  • About 13cc of raw material.

Instructions

  2. Print eight wheel rollers.
  3. Clean the holes through the centers of the rollers, and smooth the outside of the rollers if needed.
  4. Cut axles for the rollers.
  5. Mount the rollers on the hub plates. Ensure they can spin reely.
  6. Glue the two plates back-to-back at a 45-degree offset.
