Tamper Station for Quickmill Portafilter

This is one of my two designs ([Here's the other one](https://www.thingiverse.com/thing:3408844)) for a Quickmill-Portafilter stand and tamperstation.
As we all know the recommended pressure for tamping is 14kg, so I had some doubts regarding stability, but with 25% infill this thing is solid as a rock.

In the back of the station is a cutout for a rubber tamper-mat , I got mine from Amazon, its called "scarlett espresso Puck" - this can be taken out for cleaning.
