I based this off of laird's spool feeder, but my filament guides were not long enough to unclip them.
Has nice smooth round guides with clips that allow the filament to be "clipped in" making removing/changing filament spools easy.
This works with Octave & Makerbot spools and maybe others as long as they aren't much larger diameter than the Makerbot spools.
Uses 2 standard size zip ties to attach to wiring harness.
