A very simple flat surface to put a coffee scale on a Breville Barista Express espresso machine, my scale's feet don't sit right on the drip tray and would sometimes give me wonky readings. It's always the simple ones that make the biggest difference in QOL, am I right? Slides left and right nicely to go from dosing grounds to measuring the actual shot.

It's 130mm wide, you could scale the X direction up or down depending on the width you want.

It's a 2 minute exercise in 3d modeling but I included the f3d file as well.
