Prusa i3 Mk2 Z frame support w/ base plate

thingiverse

Because the Z-axis of my Prusa I3 was always a bit too wobbly for me, I decided to improve that situation. Various Z-axis supports were available on Thingiverse, but none met my standards. Since I also wanted to place the printer on a base plate that could be easily moved without recalibration, I combined the Z-axis support with fixation points on the base plate. This way, I didn't have to replace the threaded rods of the frame. The rods for the support are made from 8 mm stainless steel (1.4305) with threads cut to match, but standard M8 threaded rods can also be used. I added fixation holes on the Y corners and brackets for the Z frame itself. These parts are screwed to the base plate using M6 screws. To secure the bottom parts of the Z support, four M3 threads must be drilled into the frame. The bottom parts of the Z support are designed so that two nuts (M6 and M8) fit securely inside them.
