Auger for non free-flow powder

thingiverse

This design is intended for non-flowing powders. It's compatible with a 24/29 ground glass joint. The plan is to create a powder dispenser that delivers small amounts of powder accurately. Initially, I tried using a support structure but it damaged the auger's surface. This was problematic because an uneven and rough surface disrupts the powder flow. To address this issue, I added a shell around the auger. While not perfectly smooth, it's an improvement over the original design with the support structure. Simply remove the shell after printing. The thread pitch is approximately 5 mm. Good luck with your project.
