Spool holder for 2020 extrusion

thingiverse

My Kossel kit had an acrylic spool holder that shattered when I accidentally caught the power cord on it. Consequently, I needed a brand new replacement. For 1kg rolls of filament that are as wide as 70mm. This part will snap onto 2020 rail and mount with an M3x12 screw and a drop-in t nut. Instructions Printed at a very low .4mm nozzle temperature with an extremely thin .3mm layer height. Two full perimeter shells were applied with only a minimal amount of support used for the most difficult sections to produce a very solid construction that can hold kilo rolls. One M3x12 screw and one single drop-in t nut are required in order to attach this piece onto a 2020 extrusion rail. Be sure to include the mounting hardware, an M3x12 screw and a t nut, prior to attaching it securely to the 2020 extrusion rail. When removal is necessary, you must carefully twist upwards in order to remove the spool holder safely if for any reason the M3 drop-in t nut and screw have been overlooked during initial setup.
