Dry Box for Large Spools with Roll Base

I needed a dry box that would hold two large spools (1 kg). I found a roller base (http://www.thingiverse.com/thing:104983) that I liked however I found that it was for narrow spools so I made one using the same rollers but wider for the wider spools. I made two of the larger ones then hot glued them to the bottom of a plastic box that had a good seal (see photos). Next was to get the filament out of the box and again I found a good design (http://www.thingiverse.com/thing:318580) but had to make a change to the top cap to have a tight fit on the 6mm tube that the FlashForge Creator Pro uses. So you so you don't have to go running all over the place I will provide all the parts that I used. I made two large rollers and one small one from the original design. The bearings, rod and shaft collars I ordered from the large online retailer Am*$on (Amazon), because I am lazy. The box I got from Target.

Update: If you have a narrow spool (I have one), use the small roller (Thing:10
