Prusa i3 Bear Upgrade y motor mount with endstop

thingiverse

I like how the original Prusa MK3 uses one of the y-axis bearings for end-stop detection, but I'm not a fan of how it gets rammed into the rod holder every time the printer homes in on its position. This puts an off-center load on the y-axis. Since I'm using pekcitron's great Bear Upgrade, I've modified his y-motor mount to act as the y-axis endstop for homing. Now the y-belt holder rams into the y-motor mount. This removes the stress from the bearing and results in a centered load. I'm using this along with zbrozek's y-belt holder and tensioner, which is also a great design and working flawlessly. With source file included, I've added the .f3d source file as I hope more people would include source files in their things. Often I want to modify something and having only the .stl file makes it more cumbersome than it should be in my opinion. So don't let anyone get frustrated when they want to modify a design.
