Nema 17 Gear-Mount tool

**This tool is intended to help with mounting the gear (for example for a geared extruder) on the Nema 17 motor.**
Any bearing is sensitive to pressure orthogonal to the turning-direction. The gears I tried required some strong pressure, so I feared to damage internal bearings of the Nema 17.

*This tool helps to greatly reduce risk to damage the internal bearing of the motor during pressing down the gear on the axle.*

The tool has has a round pad in the middle to take directly pressure
