Solder Spool Holder

I remixed the awesome spool holder by Ecoss, that design works great however the end cap that just slides on and registers with 2 pins was failing with a 500g roll of solder in my tool box when I travelled, so I removed the pins from the large part and made the end cap bolt on with 3mm x 20mm bolts on the bottom and 1 on the top going into spool bar. I also removed the printed on feet since I prefer stick on rubber non slip feet, and I made the solder hole a little more robust.
