reprap guru Prusa i3 Z axis Upgrades

thingiverse

Greetings! I wanted to upgrade the leadscrew on my reprapguru prusa clone to an actual lead screw and not the threaded rod that comes with it. These mounts allow you to use the upgraded x-carriages available elsewhere (I personally used this one https://www.thingiverse.com/thing:1140733) If upgrading the X carriage with 8mm lead screws you will need to upgrade the Z axis motor and bearing mounts. These reposition the mounts to accommodate the larger 8mm lead screw. The bearing mounts also allow you to integrate a pillow bearing directly into them. (this also solves the problem with the original reprapguru's Z bearing shaft having no top cap) The designs worked on my printer (purchased in 2017) but reprapguru may have changed things. So... some modification may be required NOTE: I did have to clean up the bearing shaft holes with an 8mm drill bit (turned by hand) to get the shaft to insert cleanly. Enjoy!
