The author remixed this model.
Added a bit of a bracket with a hole in it to mount the UBBI on the top of my gantry, useful for feeding from a RepRack behind or something.
Uses a PC4 - M10 fitting.
The stock screw is too long to reuse without some kind of spacer. It's an M4 screw.
My UBBI - UBBI gantry mount can be found here.
