Coffee tamper

I just bought a nice espresso machine and did not like the tamper that came with it. so I decided to design one of my own While doing so I experimented a bit with different functions in my cad software and liked the outcome.
The base has a diameter of 57.5mm, which is perfect for my machine but can off course be altered for other machines. I designed it so that it can be printed without support.

WARNING:
PLA is not food safe so I suggest printing it in PETG instead.
