Filament Spool Holder with Dustfilter

A simple filament-spool-holder with a dustfilter.
It's especially for a "BQ-Filament"-spool, but you can use this for any Spool with a width of 73,5mm.


Use a ball bearing with an 8mm center diameter, just like a normal skateboard-ball bearing.
and M3x25 countersunk screws.
I glued the the two things between the Inside.

I apologize for my bad english...

greetings!
