Best Spool Holder for 20 x 40 Aluminum Extrusion

thingiverse

I needed a spool holder, and made this a few years ago. I lost the original file, so I re-made this one and printed it. The original worked flawlessly, and this one does too. If you have a printer with a top 20x40 aluminum extrusion like this, this is the easiest way to mount the spool. You don't need the bolt to hold it in place, but it keeps it from moving. Enjoy!
