Metal shelving spool holder

prusaprinters

<p>Mount spools on the racking of your shelving units if you have the slot together type. I don't know how universal it is, but the slot is 3mm wide, and 10mm deep.</p> <p>I purposely didn't make this supersized because physics and my shelving may not be the best of friends. It will support a standard 20cm spool that is under 70mm thick and has at least a 40mm hole.</p> <h3>Print instructions</h3><p>You need to make 2 decisions:</p> <p>1) which way the spool will unwind. Looking at the cap with the spool loaded, if the spool will unwind clockwise, use the RH thread. If it unwinds anti-clockwise the LH thread. This will stop the cap undoing and the spool falling to a big messy death on the floor, possibly taking your printer with it... or you could just use some glue.</p> <p>2) Which way do you want the spool holder to point to the left or the right. The one I printed in the image is the point right version.</p> <p>Nothing fancy needed to print this, 0.2mm layer height and PLA will do you, but you do want to solid up the bolts, I used 2 perimeters and 90% infill. For the rest of the parts, the more infill and perimeters the stronger it will be. I printed with 2 perimeters and 50% infill for everything.</p>
