Best Spool Holder for 20 x 40 Aluminum Extrusion

thingiverse

I needed a spool holder, so I created one a few years ago. Unfortunately, I lost the original file, which forced me to re-make this one and print it again. The original design worked perfectly, and this new version does as well. If you have a printer with a top 20x40 aluminum extrusion like this, mounting your spool has never been easier. You can actually use the bolt to keep it from shifting, but it's not strictly necessary.
