Fillament spool wall holder

Simple fillament holder for wall.

Required parts:
1x printed holder base (screwed to wall)
2x printed holder sides (holding spool from both sides)

3x screw to mount base onto wall
2x 608 bearing, used in skates/roller/inline/fidget spinners - quality is not important
1x M8 screw with length around 10cm (used as axis to hold things up)
1x M8 nut
3x washer, one into base, two around bearings

Screw diameter is not very important, just make it fit into bearing. US equivalent can be used.

Should fit spools with bigger and smaller inside hole.
Print holder sides exactly, or you will have hard time to fit bearing inside.

Assembly:
Wall | Screw head | Screw washer | Holder base (printed and mounted to wall) | Screw washer | Bearing | Holder side | Fillament spool | Holder side | Bearing | Screw washer | Screw nut

I'm also thinking about making air-tight case for this, to make fillament last longer in better quality. The only problem is print size required.
