"Universal" Spool Holder

Universal spool holder, it can be mounted vertically, horizontally, and on a stand. You can design your own stand for the printer you own, will design a stand for Prusa when I have some spare time.
Hardware you will need:
1. One 5/16" bolt 3 1/2" long
2. One 5/16" Lock nut
3. Two 608 bearings.
Note: If you want to increase the resistance so the spool does not unwind itself when the print head moves just tighten the nut a bit until until you feel comfortable.
