Tronxy X5S Belt geometry aligned screw adjust motor mounts

Evaluation of members on the printability, utility, level of detail, etc.

3D model description

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 critical on a coreXY design printer.
I also didn't like the fact that the X motor drive pulley was right 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 the different belt heights. I also 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 as some of the other designs on Thingiverse but I couldn't find anything that would not restrict the full travel of the gantry using the mega gantry guide blocks. The mounts are scratch designed in Fusion 360 but I've taken inspiration from a few designs on Thingiverse so I'll credit them with remix references or if unavailable, in the text.
I also noted ljbrumfield's design of mount : . These are well designed but have side mounting points that clashed with my gantry blocks. I did take some design ideas from the motor slide plate, with some dimensional changes to make it a tighter tolerance inside the motor housing (Sorry Lee, I couldn't credit you in the remix section as your licence doesn't allow it).
