Single Track Spool Holder

Single track version of the spool holder from the [Airtight Filament Container](https://www.thingiverse.com/thing:2607131), should work with most large and medium spools.

Uses 4 - [608 Bearings*](http://amzn.to/2gEukPq). Bearings are inserted from the bottom of the spool holder.
