Tronxy X5S Belt geometry aligned screw adjust motor mounts

I designed these mounts after building the other belt alignment components for my X5S. The factory supplied mounts were pretty basic and didn't make it easy to get the tensioning right, which is crucial on a coreXY design printer. I also didn't like the fact that the X motor drive pulley was at the end of the stepper motor shaft, placing a greater load on the motor drive end bearing so these mounts are designed with an offset top face to compensate for different belt heights. I wanted something that would help make the frame of the printer stiffer so the mounts have multiple fixings to the joining frame members. I looked at some other designs on Thingiverse but couldn't find anything that wouldn't restrict the full travel of the gantry using mega gantry guide blocks. The mounts are scratch designed in Fusion 360, taking inspiration from a few designs on Thingiverse, so I'll credit them with remix references or text if unavailable. I also noted ljbrumfield's design of mount at https://www.thingiverse.com/thing:2720415. These are well designed but have side mounting points that clashed with my gantry blocks. I took some design ideas from the motor slide plate, making dimensional changes to make it a tighter tolerance inside the motor housing.
