Filament holder

I decided to make my own filament holder which:
-has minimum friction
-is easy to operate when changing filament
-saves space
-minimizes additional (non printed) parts

Needed parts:
-2x bearings 8x22x7
-mounting screws m4 (I mounted mine on the printer but stands are flat, so you can screw them anywhere)

How I printed:
-rod @ .2 and with raft (strongly recommended)
-2x screws @ .2
-stands (right and left) @ .4

Additional notes:
I have corrected some minor design challenges I came across.
New Rod has corrected thread which should work at both ends (original one needed rome sanding/filing). New screw is 5mm shorter so it can tighten narrow spool holders (41mm wide spools).

Happy printing!
