<p>*** Update: 9-10-2020 Some of my thin spools I had from Proto Pasta, and Spider Maker were offset from center and caused a few issues. So I made a quick spacer that can slide onto the axle and move thinner spools closer to the center of the box.</p> <p>*** Update: 9-1-2020 After making four of these now, I ran into a little issue with one box, where the spool would rub on one side. I made my holes a little too low, and forward on one side. So it's very important to put the axle in a spool, and visually place it inside the box to make sure you have good clearances before drilling. The guide is helpful, but it helps to measure twice.</p> <p>To make a removable axle mount that would fit a Rubbermaid 21-Cup Storage Container (Part# 711717429496) and allow for easy replacement of filament spools, and smooth rotation by<br/> using bearings.</p> <p>Only tested with the limited number of spools I have on hand, no guarantees it will fit your spools. But seems to work fine with Prusa, and Spider Maker so far.</p> <h3>Print instructions</h3><p><strong>PARTS MANIFEST</strong></p> <p>All required printed parts.<br/> 2 x 60-2RS Bearing (8mm shaft diameter, 22mm external diameter, 7mm width)<br/> 6 x M3 10mm Bolts<br/> 2 x M3 12mm Bolts<br/> 8 x M3 Nuts</p> <p><em>Note: It maybe possible to use all 12mm bolts, but the bolts will extend into the box by 2mm and<br/> have the chance to interfere with the axle.</em></p> <p><em>Note: For the Axle Bolts you can use longer bolts if that is what you have. They will just extend into the Axle and have no effect on performance.</em></p> <p><strong>PRINTING</strong></p> <p>The configuration I used was as follows:<br/> PLA Filament<br/> 30% Gyroid Infill<br/> 4 Perimeter walls<br/> 5 Top and bottom layers</p> <p>Supports are only needed for the Axle Bearing Adapters.
