Spool Holder Attachment

This assembly allows the assembly of standard sized bearings and adapts to the standard Prusa Boom arm that clips to the metal frame. Mounted spools spin freely with the bearings.

The retention posts are designed to allow flexibility relating to spools of material used. The retention posts have graduated ridges of different diameters from 34 to 60mm in 2mm diameter increments. Spool holder also allows for spools up to 80mm wide.

Inspired by many community spool holders that include bearings. Not perfect, but perfectly good.
