Extruder Nema17 Creality Ender CR-10 MK8 Un-Tensioner M3

Hello UPDATE: I included a Extruder Test Wall, this is so you can print and test the tension for under and over extruding. Adjusting as needed to get a nice tension. (PS its the flat side of the test wall you want to be watching) This is a extruder un-tensioner. (It pulls the tensioner) After upgrading my extruder it sound like an old typewriter missing steps, the reason was the tensioner just is too tight for 0.75 filament. When the tensioner is tightened up by the screw alone it was too tight. I had to loosen the tensioner screw a few mm and make this un-tensioner to with a 30mm M3 screw and nut. It just fits with a 30mm bolt. But seems to have done the trick. Use at own risk Enjoy
