Mazzer Philos Doser Cup Ring

The new Mazzer Philos coffee grinder is awesome. My only reservation is the dosing cup which doesn't have a ridge that would prevent it from going all the way down into the basket, and then making a mess when pulled up.

This current model is a ring with a countersunk rim shaped like the top of the basket.

The photos are of a first attempt printed in TPU with 0.25mm height at 20mm/s. We may try with other materials, but TPU is soft and nicer. You may need to adjust the "internal compensation", or equivalent, on your slicer to make the ring fit tight.

The OpenScad source is attached if you want to customise or adjust.
