Quick release Anti Filament Unravel/tangle

thingiverse

A compliment of an awesome spool holder for flashforge dreamer, http://www.thingiverse.com/thing:948937 Which I used M8 threaded rod + 20mm pvc pipe + end cap drilled a hole in the middle for my spool bar, I designed this quick release anti-tangle cum feeder for it 20mm pvc pipe was always my favorite materiel for spool holder, the feed/anti-tangle is a add-on so I don't have to worry about my filament un-spooling while retraction or long travel that my printer does. Print Settings Printer: Flashforge Dreamer Rafts: Doesn't Matter Supports: No Resolution: 0.3 Infill: 50% Notes: Infil I recommended 80% or more it might snap if you are to hard on it Post-Printing Print 2x arm and 1x front part Front arm have clearance of 80mm (wide) and arm have clearance of 100mm diameter (the biggest spool I have) front arm will be a tight fit, sand it until it feel right, slide in a cable tie to lock it in place, the arm also have a cable tie hole but after printing I don't see a need to put a cable tie on it front arm hole are fine as it is for 1.75mm filament, if you have a extra Teflon tubing cut around 5cm and enlarge the hole just enough to fit the Teflon and slide it in like I did in the picture
