This is yet another filament holder, but one meant to be bolted onto 20x20 extrusion or the 20mm side of 20x40 extrusion. It's very similar to my TEVO Tornado / 20x20 filament holder that clicks into place instead of using a bolt
For this filament holder, print with it placed on it's back with supports at a 15 degree overhand threshold and with a 1cm brim for best results. I also included a test piece to see if the filament holder will fit on your printer.
