Prusa MK3 Y-Axis Motor Mount (juiced)

thingiverse

I repaired one file that didn't impact printing and implemented my design for a Y-Rod holder using inset/blind nuts. The Prusa MK3 is a complete disaster in my opinion, plagued by numerous problems. I'll save my complaints about those issues for now. To me, this was a major weak link that only added to the existing problems. So, I created a much stiffer y-axis motor mount that's rock solid and solved some of the misalignment issues with the factory motor mount. You can use the same mounting holes, but I recommend drilling a third hole for this mount - it's not essential. There's an excellent write-up by RHDreambox on the Prusa forum that deserves credit - check it out for more fixes he accomplished. He was a key 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 may need to use a 12 mm M3 screw instead of the 10 mm M3, as this mount is slightly thicker and requires a longer screw. The rest is straightforward. I printed with Slic3r PE, 50% infill, using Carbon Fiber PETG at .2mm layer height with 3-4 walls.
