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.
or you can go to (http://www.instructables.com/id/Frame-Mount-20201515-Universial-Spool-Holder) for build instructions.
if you are looking for a shopping list, The attached CSV file has all the stuff you will need.

Found issues with the M8 screw in the BOM. The part number was incorrect. The screw should be a fully threaded screw. The old part number was not. The problem has been fixed.
