Filament Rail mount with guide on Prusa Mk3

This is a 4-5 spool filament holder mount on top of Prusa i3 mk3s. Filament sits on bearings for smooth rotation. Spacer and bearing can slide on the rod for adjustable spool width. The clips on rod are to keep spacer and bearing in place.

I picked two of my favorite out of hundreds of filmanet holder/guide designs out there and remixed them for my needs.

I bought the hardware from Amazon:
8mm x 500mm rod

Head to the original design for spacer and clip:

This is the original filament guide I modify for clipping to prusa frame.
