All in one filament storage and spool holder

I wanted to have something that would make it easier to switch color filament. I decided to create a storage system that doubled as my spool holder. I got the idea from Tom's video here:

(BTW, I found the hot glue doesn't work as he does it so I screw my dowel holders in.)

After using it for a while, I found that there was a little too much drag on the filament coming through the hole in the box, so I made a stand that tilts the box about 45 deg
