Eureka Mignon grinder hopper for silicone bellows

A full single dose kit is expensive, and 3D printed bellows are not good.

I bought some high quality, yet generic silicone bellows from Aliexpress for 8€ and modeled this to fit them.

Printed with no infill, 3 perimeters, and PETG.

I later also brushed on a thin layer of resin epoxy inside to make it less porous and more food-safe. If you care about food safety,  please use the appropriate materials and settings.

EDIT: Feb 16 2024: Improved! Made feeding of beans much better when using an angled base.
