Spool holder for 2020 extrusion

My Kossel kit had an acrylic spool holder that broke when I caught the power cord on it. So I needed a replacement. I modeled this in SketchUp.

For 1kg rolls of filament that are up to 70mm wide.

Snaps onto 2020 rail and mounts with an M3x12 screw and drop-in t nut.
