Universal Segmented Auger

thingiverse

I'm extremely eager to test out MTO's screw design, so I decided to give it a try. The goal was to tweak the profile to match what I'm used to seeing on commercial auger screws. This turned into an exciting adventure of adding variables to customize the shaft, flights, mounting holes, pitch, and more features yet to come! I printed the screw at its maximum length for my printer, about 8 inches, with 5-inch flights. Next up, I plan to print a 5-inch length with 8-inch flights and make the flights thicker. No supports were needed - what a pleasant surprise! However, the thin cross-section did leave some holes. Thicker cross-section or a smaller diameter should help solve this issue. I'd love to hear your feedback! A huge thank you to MTO for creating this design in OpenSCAD and making it available!
