Spool holder

Hello,

I made Frame holders for 4-5 pieces of spools with bearing rollers on pipes/bars. Fix on frame by longer M3 screws into the original holes in the frame. I tested it on my Prusa MK4, for MK3 I based it on the model only, not tested so you can try it and give me report thanks :) 

You need:

2 pieces of pipe or bar/pipes with diameter 10mm and length 375mm of each.

Bearings 6000 (with inner diameter 10mm and outside 26mm) for rollers

4 pieces  of M3 screws with ideal length 25mm + nuts + washers

Advice about tracking of filament:

You can change shape of original filament guide (See image)

Maybe, I will make some better guide for this solution in the future.
