Static/Dynamic imbalance demo

Demonstration set for feeling the effects of static and dynamic imbalance. As demonstrated in this video:

You need:

Printed:
2x Handhold.stl
1x Square Tapered shaft
1x Iwheel

Purchased:
2x 625ZZ bearing
1x 5mm diameter, 380mm long, length isn't critical
M8 nuts and bolts to go into the Iwheel

The eccentric Iwheel has its square hole off-center, and the runout Iwheel has its shaft bored at an angle. These demonstrate that an eccentric shaft creates static imbalance, and a non-concentric shaft creates dynamic imbalance.

The name Iwheel comes from a different video, where I use two of them with M8 bolts in different positions to show the idea of the moment of inertia, which has letter I. This video is here:
