About this 3D model
Replacement lid for your aweseome eureka mignon coffee grinder. I don't know if it fits the 300g and 500g hopper, I only have the 250g one. If it's 120x120 I guess it'll fit. Might need to scale it a tiny little bit depending on filament/calibration. The grind setting dial your're seeing at the bottom of the first pic is from: https://makerworld.com/en/models/29443#profileId-25853
