Smooth motion plastic filament spool holder - expandable.

SummaryI designed this spool holder to allow me to expand to multiple spools. It also allows for quick and easy spool changes on a single spool configuration. I chopped the corners to eliminate one sharp corner, after I made mine. I plan on making this into a multi-spool holder when I add my Krakken print head.

This is based on 1/4 20 threaded rod and 608ZZ bearings.
