Universal Filament Spool Holder

Hi,

Find the latest version here.

a friend of mine made this universal filament holder. You can mount filament spools in a wide range. For maximum rated dimensions see attached picture. I tried up to 2.6kg material spools without an issue. For smooth unwinding it uses ball bearings.

What you need:
- M8 threaded rod
- 2x M8 nut
- 2x skate board ball bearing 608ZZ
- 8mm (core)
- 22mm (outer diameter)
- 7mm (width)
