Eureka Mignon Single Dosing Hopper

Single dosing hopper for Eureka Mignon espresso grinders.

I wanted a hopper that would efficiently funnel a specific volume of coffee beans (around 18g) into the burrs, while maintaining a straight up and down profile from any angle, so I built this in OpenSCAD, using the excellent Round-Anything library by Kurt Hutten (https://github.com/Irev-Dev/Round-Anything), and it's available as a Customizer if you want to try tweaking it to make it perfect for your dose and grinder.

Printing:

Print upside down on the print bed, no supports needed, use a food safe filament and nozzle, with fine layer height for best results.
