Summary

Yes, my BiB ONE is still alive :)
And this is one of my New Year resolutions: finally solve the problems with filament spools.

I use 2 types of spools: small spool is 19cm diameter, big is 30cm.
This holder is designed to be compatible with both types.

BOM:

• M6 x 40mm - 4 pcs
• M6 x 70mm - 2 pcs (I used 70mm of M6 threaded rod)
• M6 nut - 6 pcs (or 8 pcs)
• M6 washer - 16 pcs
• 6x13x5mm bearing - 8 pcs

• 6x19x6mm bearing - 16 pcs

• M4x70mm hex key screw - 3 pcs
• M4 nut - 3 pcs
