Prusa i3 Bear Upgrade y motor mount with endstop

thingiverse

I don't like that the original Prusa MK3 uses one of the y axis bearings for the end stop detection. This means that the bearing gets rammed into the rod holder everytime the printer homes his position. This puts an off center load on the y axis. Since I'm using pekcitron's great Bear Upgrade I have modified his y motor mount to act as the y axis endstop for homing. Now the y belt holder ramms in to the y motor mount. This removes the stress on the bearing and results in a centered load. **Thank you very much pekcitron for making your design open source which makes such modifications very easy!** I'm using this in conjunction with zbrozek's y-belt holder and tensioner. Which is also a great design and is working flawless. **With Source file** I have added the .f3d source file as I hope more people would add source files to their things. Often I want to modify a thing and having only the .stl file it's more cumbersome than it should be in my opinion. So I don't want anybody to get frustrated when they want to modify the design.
