PrintrBot 2pc Basic Spool Holder

This is a basic spool holder specifically designed to fit onto a Printrbot Simple Metal Z Axis guide rail. Its designed 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
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.


THE FILAMENT RETAINER BAR NEEDS TO BE USED OTHERWISE FILAMENT WILL WRAP AROUND THE Z GUIDE RAILS AND MESS YOUR PRINT UP! Believe me, its happened twice to me: one time wasting almost a whole print, the second time the filament snapped, breaking at the very top of the extruder assembly. It was a pain to get it out. So I redesigned it to have this filament retainer bar!

Assembly:

Just pop the Spool Holder onto the Z Axis Guide Rail.
