Hamster Wheel Extruder Visualizer/Motor Knob

Hamster Wheel Extruder Visualizer/Motor Knob

Includes 4x Wheel designs + Hamster and Mouse critters.

Designed for Sovol SV06 line of printers.
Should work with most NEMA 17 dual shaft extruder motors (5mm w/ D-cut).
Print and press fit, no magnets/glue required.

Instructions

• Size adjustment may be required. A fit test model is provided.

• Designed for 0.2mm layer height with color-change at 2.4mm.

• Strong, heat resistant filament is highly recommended (PETG, ABS, etc).

• Supports should not be necessary.

Assembly

1. Print 2x spacers + any wheel and critter.

2. Put the critter on the wheel shaft between the spacers (spacer > critter > spacer).

3. Remove stock motor knob. It pulls off but might require some effort.

4. Press the assembled wheel on the motor shaft. Ensure the flat edges are aligned.

Potential Issues

• The wheel shaft is not entirely round. I think this improves the animation, but also makes it prone to seizing (especially with fast retraction).

• For smooth, consistent rotation, you must get a good fit between the ring on the critter and the wheel shaft.

• Removing/minimizing seams is also important, especially on the inner critter ring. Sanding may be required for best performance.

• If your XY accuracy is poor, you will struggle.

• If your bridging is poor, you may require supports for the wheels.

• TL;DR: This might require some effort to get consistent results.

Disclaimers

• This concept has been done countless times already and the originator is unknown to me. I was specifically inspired by TayGO's version on Thingiverse.

• The geometry is all original. It's quite rough. Apologies if this makes modifications difficult.

• Made in Blender.

Thank you for your attention, bye~
