Z Top with 688 Bearings for Prusa i3 MK3 Full Bear Upgrade 2.0

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3363307.

This is a redesign of the Prusa i3 MK3 Full Bear Upgrade z top supports to accept a 688 bearing. I haven't finished the upgrade yet so the parts haven't been verified for alignment, nor have the clearances been checked. Wanted to get it out for the community to use. If you print it before I can, let me know if everything lines up.

I've included the .f3d, .step and .stl formats. If you use Fusion 360, the .f3d file has part already mirrored. If you don't use Fusion 360, just mirror the .step file.

Update June 2019: I added the files for the MK2/2.5 upgrade as well. All have been printed and test and working well. Enjoy!
