The 3D printed single dose container for the Eureka Mignon Specialità consists out of two parts. One part sits on top of the grinder instead of the original coffee bean hopper. The other part is removable from the first part and is used as a container to dose the coffee on a weight scale. Once the weighing is completed, the container can be put upside down on top of the first part. The beans will fall into the coffee mill and the dose container covers the filling hole to ensure that no beans pop out during grinding. See also: Single dose adapter for eureka mignon
Food Safety of 3D printed materials:
Although the 3D print material itself (Prusament PLA) is food safe and even biodegradable, the fine gaps between layers are problematic. I’m using the single dose container for my Eureka coffee mill without any further treatment after the 3D print, but it is recommended to coat the 3D printed container with Epoxy or any other coating which seals the fine spaces between layers from the 3D printing.
The here offered single dose container is untreated and not coated with any surface sealing.
“Even though PLA is biodegradable, and the material on its own is food safe, we suggest not to drink or eat from your 3D prints repeatedly. It’s because of the small fractures in the print surface, which means bacteria can build up in there over time. You can prevent this by applying a food-safe coating.” (Source: https://prusament.com/materials/pla/)
Don’t put PLA printed parts into the dishwasher or microwave.
