Ninjaflex helper for Printerbot simple (alu extruder v1)

thingiverse

** update Dec 5, 2015 Added a model that has a bit more clearance between where the guide ends and direct drive + bearing start. Not sure if this was an issue for anyone, but if you're having difficulty with the original model, try the 'more clearance' stl This is a guide for the Printrbot simple alum extruder (V1). It should improve the reliability when printing with Ninjaflex. (still have to test it out on a long print) https://www.youmagine.com/designs/printrbot-alu-extruder Don't forget to remove the small support that's in one of the holes after printing. guide will work without the .STL "bar" ... but if you want to use it, you may need to file it down a bit. Guide can be left in place when printing with other filaments (1.75mm). Print Settings Printer Brand: Printrbot Printer: Simple Black Rafts: Doesn't Matter Supports: No Resolution: .3 Infill: 100% Notes: Printed on Printrbot Simple (1405). I printed the guide in PLA/PHA from Colorfabb.... regular PLA should work fine too.
