Prusa MK3 Y-Axis Motor Mount (juiced)

myminifactory

I think the Prusa MK3 was a total failure on many fronts. I won't go into those problems right now. For me, this was a critical weak link that just added to the existing issues. So, I designed a much stiffer y-axis motor mount. It's extremely solid and fixed some of the mis-alignment 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 necessary, though. There's a great write-up by RHDreambox on the Prusa forum that I give credit to where it's due - check it out for even more fixes he did some excellent work on all 3 axes. 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'll need a screw that's just a tad longer. The rest is easy going. I printed with Slic3r PE, 50% infill, with Carbon Fiber PETG @ .2mm layer with 3-4 walls.
