Yet another Extruder Visualizer. I did it for my Prusa i3 Mk3, but there are others that it should fit. I thought it might be cute to make a Hampster Wheel one. And before you say there is no P in hampster, you have never had one.

I'm using the standard 8x3mm magnets.

It would be cute if the wheel moved and the hampster stayed put, but that would require a pivot point and I might see what I can come up with.

I did it in Onshape. Just playing around.
