Bowden Extruder (2020 Extrusion)
Description
**Update 10/27/2018: ** *Use the _Updated version of the files, as they fix an issue where the bearing would slip to the edge of the filament and cause the extruder to lose grip, as well as increasing the grip by 'tightening' the spring.* **OG message:** I wanted to create something for practice, and I wanted to upgrade my extruder to handle flexible filaments better. I *haven't tested it with flexible material* yet, but it works fine for PLA, and I presume it would work for ABS, PETG, etc. This is the fourth iteration- The previous three didn't have enough grip on the filament with a MK7 drive gear due to design flaws. (They aren't posted to Thingiverse) Feedback is greatly appreciated!
