About this model

This is a remix of "Expandable Auger" by ROBK636. I did a quick edit to include M3 captive nuts and M3*12mm screws for easier assembly and a cleaner look, as well as less chance of material getting stuck on the screws and nuts. Upscaled to 2x. The pitch and diameter of this one is 50mm. The STL contains tons of internal edges and faces because of my lazy and quick CAD work, but it sliced fine in Cura 2.5.0 (an old version). Gcode that works on my Tronxy P802M is included. End pieces currently not included. I'll design end pieces as well as a tube flange with a bearing when I get time.
