Printed with .6mm nozzle in PLA with tree supports for only the faceplate (text facing up).

I suggest printing the sliders/switches in a different color than the baseplate

I also suggest color changing, or pausing and changing filaments, at the text layer for text to be more visible.

Large magnet spot for the back for a 25mm ceramic magnet. Other file is the same without the spot for the magnet on the back.

I used 4x2mm magnets (x9) so when the sliders move, they magnetize into place plus they give a satisfying feeling of it snapping into place like a switch.

Here are the magnets I used
