Spool Shim

thingiverse

I designed this shim to reduce the hole size of my spool of filament with a 73mm diameter. My spool holder couldn't firmly hold a spool with a hole larger than about 60mm, so I created this shim to fit snugly inside. To secure it in place, I pounded it gently into position using a rubber mallet for a firm grip. The ends are chamfered for easy installation. I made mine from PLA, but a slightly more flexible material might be even better suited. Since there may be other sizes needed, I created a .scad file, although I've never done so before, and here's hoping it works as intended! Suggestions would be greatly appreciated!
