Flywheel cage crush gauge

Ever build a flywheel cage and then totally forget its crush down the line? I made this gauge to fix that! Now you can easily measure the crush of any flywheel cage whether it's installed or not, so no more trying to measure 0.5mm by eye.

Here's how it works:

If your motors are already in, just line up their shafts with the holes on the gauge.

If the cage is empty, the raised circles on the gauge will slot right into the center of the motor wells.

I've tried to cover almost all the common crush sizes for both standard and mini flywheel cages. I also connected the gauges so they don't get lost, but they're still flexible enough to bend for those tricky measurements.
