Offline's Bowden Extruder

thingiverse

I designed an entirely new extruder that caters specifically to my needs. Its primary design emphasis was on ensuring easy maintainability, with the inclusion of a quick release mechanism and a sliding rail for connecting the body of the extruder to its holder. In the accompanying images, I must point out that there are no springs present; these should be strategically added between the quick release and the bolt heads. The design relies on M3 round-headed Allen key bolts.
