AM8 horizontal Y belt remix

I don't have any 625 bearings for the original file, but I had a few 605zz bearings left over from a B2D extruder kit I got a while back. So I remixed the file to fit the smaller bearing. Thanks to the creator for publishing the step files, as it was super easy to modify!

I also added a version of the tensioner with tighter tolerances on the holes, and added an M5 socket head cap screw in the middle to be pushed against rather than just plastic. This requires an M5x16mm socket head cap screw and M5 nut. The M5 short version does not require a nut, and only uses a M5x8-10mm screw. Also added an extra, thick fillet to a part of the motor bracket. It should slightly increase strength.

This has not been tested, I just remixed this now in case I want to do this mod in the future.This does not fit my printer because of the y-carriage plate I have installed (no cutout in front). So definitely cannot test! D:

Update 6/26/2019: Added v3 of the motor mount, removed tab that was cut out for original creator's endstop mount. Mine is mounted differently, so I added it back. Also added a chamfer at flat faces to make removal from bed easier.
