Clip-On Spool Roller

Quick and easy way to hold a filament spool on any 2020 extrusion. Uses clips not screws for quick installation and change.

- Fits spools from 50-74mm wide using four different width sets of rollers. -- Make a set of each in a different colour. - Works with all 2020 v-slot extrusions. - Parts are small, strong, and print quickly.

Uses cable ties for assembly - orientation as per pictures. Needs four 624 ball bearings (inside diameter 4mm, outside diameter 13mm, width 5mm), two M4x60mm socket head cap screws, two Nyloc nuts and four washers. The string prevents the parts sliding apart and makes handling and storage easy. Aim for 110mm between the centres of the rollers. Starting with a 300mm long piece of string (preferably 1.5mm diameter or less) gets you into the right ballpark. <br /> <i> For a quick-release, clip-on spool hanger, see https://www.thingiverse.com/thing:7042254</i>
