PrintrBot 2pc Basic Spool Holder

thingiverse

This is a basic spool holder specifically designed to fit onto a Printrbot Simple Metal Z Axis guide rail. It's created so that you don't need to use a ton of plastic to print out a spool holder. There are two parts: The Spool Holder and The Filament Retainer Bar. The angle of the spool holder keeps the spool on the spool peg. The retainer bar can be used either with the long or short leg in the spool slot so it can be used with most filament spools. The retainer bar prevents the filament from wrapping around your Z guide rails. Using the Filament Retainer Bar is crucial - without it, filament will wrap around the Z Guide Rails and mess up your print! I've been there twice: once wasting almost a whole print, the second time the filament snapped at the top of the extruder assembly. It was frustrating to get it out. So I redesigned it with this Filament Retainer Bar! Assembly is easy: Just pop the Spool Holder onto the Z Axis Guide Rail. Slip the Filament Retainer bar into the Spool Holder's upper slot. Drop your roll onto the Spool Holder making sure the filament feeds from the top. Make sure the Filament Retainer Bar covers the whole filament area of the spool so that the filament is retained between the spool and the retainer bar. You're done! Print Settings: Printer Brand: Printrbot Printer: Simple Black Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2mm - 0.4mm Infill: 15% Notes: Print at whatever standard settings you use! Print with the Z-Axis Guide Rail hole-side down, so you'll need to rotate it in your program!
