Eureka Mignon Specialita Tilted Base 10/12/14deg

The original model is a fantastic idea, yet I it lacked the PCB holder. Instead of adding a tilted stand to your grinder, just replace the original base. As a benefit, the button is moved to the front left, which at least for me is preferable position.

Original author was kind enough to share the step file with me, so here I am, sharing my improvements with the world.

Note: Some Mignon variations are apparently not compattible with this arrangement. On my Specialita manufactured in 2025 it worked fine, since my grounding wire is recessed about 2cm from the bottom of metal base. This comment mentions that "Eureka Zero 55s" has the screw with grounding wire level with the base, which will not fit nicely without some tinkering.

Mounting instructions are same as original, i.e: the same screws, just a new binder.

Print in your favourite material, I am able to print without brim but your mileage may vary. 

I got best results with PETG, 0.15mm height, 1.02 overextrusion for extra rigidity, 0.04mm thick fuzzy edge on the outside painted with smart fill for a nice ‘frosted’ finish (TBH, this is my default for all prints - nicely hides layers)

I present you with three inclinations:

• 10 degrees is my photo. Better stability, better feeding of coffee from stock hopper

• 12 degrees - midway throug

• 14 degrees - original model. Possibly lower retention, but worse cofee feeding from stock hopper.

I have created a compatible tray - print tray in 0.2 layer height for best results, and attach 3mm silicone cabinet bumpers or similar to bottom of your grinder.
