Double bearing filament guide for the MK3S+. I haven't tested it on other Prusa models like the MK4 but it likely fits them as well.

 

I printed at 100%, supports are not totally required. See the photo gallery for recommended print orientation.

 

Hardware required:

  • 2 x M3x18mm screws
  • 2 x M3x4mm heat set inserts
  • 2 x 608-2RS skateboard bearings
  • 2 x small zip ties, the same size as in the Prusa kits.
