Filament Spool Roller using 608ZZ bearings - Snapped together and no bolts

I created this filament spool roller using 608zz bearings because I didn't like any of the ones out there and this also doesn't use any bolts. Everything snaps together. This was printed with ABS for strength and durability but you can also print this using PLA.

I've also include a new side and bottom base (Update 08-24-2017) for those whose want to use these spool rollers inside the Rubbermaid 21 cup dry food container for high moisture absorbing filaments. The Rubbermaid spool rollers were printed with yellow PETG.
