Ergonomic espresso tamper

As someone with mild arthritis, my wrist starts to hurt after pressing maybe 200 of these pucks per day, so… I made one that fits my hand perfectly to reduce as much weight while retaining my usual 30 pounds of pressure as best as I could.

You can scale this model to the exact diameter you need in PrusaSlicer 2.6 (currently in alpha 3, highly recommend) Use the Measuring tool to scale the SECOND TO BOTTOM MOST RING and adjust to either 57mm or 53mm depending on your espresso makers parameters.

Enjoy!
