About this 3D model

Okay so the Prusa MK3 in my opinion was a complete disaster on many levels. I won't complain about those at this time. To me this was a major weak link just adding to the issues. So I made a much stiffer y-axis motor mount. It's rock solid and fixed some of the mis-alignment issues of the factory motor mount. You can use the same mounting holes but I suggest to go ahead and drill a third hole for this mount but its not a complete necessity. There is a great write up by RHDreambox on the Prusa forum. I give him the credit where it is due - check it out for even more fixes he did good work on all 3 Axis's. He was a main contributor to this file and thought process. https://shop.prusa3d.com/forum/original-prusa-i3-mk3-f30/fine-tune-your-mk3-y-axis-t13851.html#p63653 Fine Print:You might need to use a 12 mm M3 now instead of the 10 mm M3, this mount is a bit thicker so you need a tad bit longer screw. The rest is gravy. I printed with Slic3r PE, 50% infill, with Carbon Fiber PETG @ .2mm layer with 3-4 walls.
