The Eureka Mignon series is one of the best value grinders in the market, but it’s a multi-dose design. Many home baristas single-dose shots now, for convenience and consistency. Niche Zero waiting lists are long, and they’re $750, with the new Mignon Single Dose design going for $850. So why not supercharge an Eureka Mignon?

This three-part kit will turn any Eureka Mignon coffee grinder into a single-dose, zero-retention powerhouse. 

• Redesigned base with 15-degree tilt (like Mignon Single Dose) 
• Screw-in button plate to always press the front button, enabling easy on/off toggle operation through the side switch (like most single-dose grinders)
• True zero retention with bellows (18.0 g of beans in, 18.0 g of grounds out) blowing through the Eureka-compatible 20+ gram hopper with anti-popcorning lips (no beans jumping out when grinding) that fits Harris® bellows https://amzn.to/4aFnaVs and 3 oz glass jars (~55 mm diameter) https://amzn.to/40XgD5h , perfect for pre-weighed espresso doses
• Shorter height than Eureka Mignon with medium hopper
• Works great with my Puck Prep Station https://www.printables.com/model/1156302-rancilio-silvia-bottomless-portafilter-espresso-pu  for grinding directly into the basket using a funnel attachment like this one https://amzn.to/3Egk266 
• PETG or PLA recommended - only sparse infill required if printed with 3mm walls

This kit has received (unofficial) praise from Eureka product executives for its simplicity, effectiveness, and design style.
