Gear bearing spool holder for Prusa Mk3 modelo 3d

I used Prusament PLA for printing, with  0.1mm DETAIL MK3 settings, Slic3r Prusa Edition 1.41.2 Results with 0.1mm are better than 0.15 DEFAULT MK3. You will need to print two bearings per spool. The planets will sit quite tight. Let the part cool down, carefully loose them. I used the flat side from a screwdriver to pop the planets a little. The use the bearing helper tool to even things out with an electric screwdriver (6mm) for a few minutes.
