51 mm Coffee Dosing Cup Adapter for the Femobook A2 grinder

This is intended to be a drop-in adapter that replaces the stock plastic receiver of the Femobook A2 grinder, letting you use a standard 51 mm stainless steel dosing cup. I did this because I found that eliminating the plastic greatly reduces static buildup, which was my main issue with this grinder.

Parts to print:

- Cup holder
- Spacer

No supports needed. Can be printed in PLA.

Bill of materials

- 1× 51 mm stainless steel dosing cup (the model was built for this cup: https://www.amazon.fr/dp/B0GJDDHHR7)

- 4× round magnets, 5 mm diameter × ~3 mm height (optional) — fit into the four holes in the cup holder with a small drop of glue; attach the adapter to the grinder. (I used these ones: https://www.amazon.fr/dp/B097MJLY51)

Note: magnetic hold is weaker than the original receiver.
