Spool Cradle (Improved)

A spool cradle design that uses flanged 608 bearings for lower friction (F608Z). Also fits inside a Rubbermaid 21 cup sealed food container to protect moisture sensitive filaments. Flip the side pieces and adjust beams to accommodate your spool widths.
This is an updated version with stronger bosses. Optimally, the beams should be printed at a .3 layer height. Printing at other layer heights will alter the thickness of the beams. My beams were a nice tight fit in the slots, but you may need to shave/adjust them depending on your printer's settings.

The ideas came from the designs I have credited below.
