3D model description

I grew really tired of the original UM2 Bondtech motor mount having it's nuts slip out over time. So I designed my own.

Normally I would use metric as the rest of this printer is metric. But this uses Imperial screws and nuts as they provide a bigger surface area to hold the mount together without trying to get a nut and washer inside the mount base.

This assumes you have the QR Ultimaker 2 Kit:

Non-Printed Part List
Two 6-32 screws of 3/4 inch long
Two 6-32 nuts (not lock nuts)
