Universal Spool Holder (2020 AND 1515 frame mount)

This spool holder will attach to a 2020 / 1515 aluminum extrusion frame. It will hold all 1kg (2.2lb) spools of filament. it is even capable of clamping the 1lb Taulman filament spools.

Every time my printer retracts I see the spool move. Very free movement and I have had no tangles with the one I have been using.

The BOM and Exploded diagram are attached. They can help you assemble the holder.
