I'm using the CAFEDEKONA (aliexpress link) tamping station however the Decent Espresso bottomless portafilter never fit perfectly / easily goes out of level.
I wasn't happy with stock the adjustable screw either.
The tamping /portafilter ring as well as the handle rest perfectly fit the portafilter, making sure it is level and doesn't move out of place.

Material: Polymaker Polylite PETG

Handle rest and peg:
I used superglue to permanently attach the peg to the handle rest. A screw would be too big unfortunately.
