The hamster wheel for my daughters class pet was squeaky and barely held on. Since it's a very small hamster, I did not find any small enough wheels that could hold onto the cage. Hence I've designed something myself.
Wheel specifications
- Wheel outer diameter: 130 mm
- Wheel inner diameter: 124 mm
- Wheel depth: 50 mm / 65 mm
- Spindel diameter: 10 mm
- Spindel cage thickness: 1.1 mm
- Spindel cage bars minimum distance: 10 mm
Print specifications
Material:
- PETG or PLA+
- PLA might work, but might snap when attaching the spindle due to the surface tension.
Print settings:
- Spindle:
- Designed to print it upright with minimum off supports
- Designed to print it upright with minimum off supports
- Wheel
- Just print on its back.
- No supports needed for the small one.
Due to the rounding on the bigger one, supports are required to make the arc a bit decent. - Add fuzzy skin (PrusaSlicer 2.9+) on the inside for grip. Included in the 3mf/gcode file.
Assembly
- Hang the spindle to the cage by putting it through the cage and twisting it 90°.
- (optional) lubricate spindle with a tiny bit of silicone spray for minimal friction.
- Just press the wheel onto the spindle.
