Raising plate for LK systems S1 room thermostat

A simple 3mm raising plate or extension frame for a LK systems S1 thermostat. (Scandinavian brand.)
The wires comes out in the center of the thermostat and they will get pinched by the back of the housing if installed this way so I made a rough frame in tinkercad.
As you can see on the last picture the corners of the frame is a little bit larger than the back of the thermostat due to the housing being slightly curved. I will sand the corners into an acceptable shape.
