Filament Guide Cleaner for Printrbot Simple Metal

youmagine

I designed and printed the fantastic Universal stand-alone filament spool holder from Creative tools (http://www.thingiverse.com/thing:508896) and have been thoroughly impressed with it - it's incredibly well-designed, looks outstanding and delivers everything you can ask from a filament management system in one! My only concern was that the Printrbot Simple Metal requires the filament to come from above & behind the print head, and the spot I've chosen for the spool holder is too low, and off to one side.I wanted to stick with the fantastic design, and make it perfect for my Printrbot, so I combined this design. The idea is that the spool holder can live almost anywhere now, and I feed the filament at the rear of the machine, up through a hoop on the rear Z-axis rod and into the new design part mounted on the front Z-axis rod which guides, cleans and lubricates the filament before placing it in just the right spot for the print head.I added a 2mm PTFE tube to the front of my guide, which means that the filament glides smoothly through and doesn't grab or grind on the front of the guide, which it will do when the filament is pulled at a sharp angle.Thanks again for the great tool overall Creative Tools - I hope my combination here will encourage others to try the management system.
