Eureka Mignon Coffee Grinder Single Dose Mod Kit V2

OK coffee geeks, here's a twist on Eureka’s brutalist art deco style, in 3D-printable kit form.

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. 

• Minimalist 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)
• Includes Brutalist Cup Base to elevate single dose cup, while neatly fitting the 15-degree base mod for stability and no spills
• 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 acrylic hopper
