For a hassle-free, cleaner, and more precise single dosing experience, replace the stock hopper on your Eureka Mignon grinder with our 3D printed single dose hopper. Not only is it more compact, making it easier to use in situations with limited headroom, it also allows you to get precisely what you put into the grinder for each dose, up to an incredible 0.0g retention on each grind* when combined with our premium custom made silicone bellows.

We only want to bring you the best experience, so after a long process of testing 10+ iterations over several months, this latest version combines simplicity with many built in features.

[Features]

Not too small, not too big. Just the right size to support your single dose of beans while exposing the bellows just the right amount to be pumped easily.
Has a built in bean buffer chamber that holds ~20g of beans, enabling you to do cold starts with the bellows fully seated in the hopper which acts as an anti-popcorn device.
Maximized funnel surface area to make it easy to pour in beans. Slope is steep enough to support the angled base mod
The single dose hopper replaces the original stock hopper while maintaining its square and chiselled aesthetics.
Low profile design allows a greater clearance compared to the original full-sized stock hopper.
Simple installation, taking less than a minute and requiring no additional tools.
Performs best with our silicone bellows (which also perfectly fits the Niche Zero and Duo) for up to 0.0g retention*.
No modifications necessary for installation and use, but for best performance, see disclaimer*

Adding Optional Bellows Later

If you already own the hopper and would like to add the optional bellows, you can purchase it separately here: Silicone Bellows for INTROVERT Single Dose Hoppers

[*Disclaimer]

In some situations like listed below, retention may vary from 0.0g-1.0g
Zero retention can be more easily achieved with the removal of the de-clumper or "ACE system", which requires some disassembly and reassembly. With the de-clumper still in place, you may notice a decreased performance of the bellows and higher retention
Grinding after cleaning the insides of the grinder will cause more retention for a few doses
Grinding after changing grind size may cause some retention
Using darker roasts may cause more retention than lighter roasts
RDT method not recommended
Achieve the best results with lighter roasted beans and at a consistent grind size setting.
Listing does not include the grinder nor the stock hoppers in the photos
