CTC Prusa Z motor mounts

thingiverse

I'm not thrilled with the nut trap slot setup on my CTC Prusa i3 (plywood frame) either. The z motor mounts are built to be a lot more robust, and they bolt directly into the existing frame holes using a through bolt/nut combo - significantly stronger and sturdier than before. They also provide a much tighter hug for the motor itself. Depending on how they print out, you might need to do some light sanding on the tabs that stick through the frame and the back motor supports. Fortunately, my prints didn't require any work in this area.
