Based on my IKEA Tradfri button template

A simple shortcut button made for the IKEA Tradfri remote so I could turn it into a shortcut button.

Print settings

For the colors, use M600 color swaps between the parts. This is perfectly doable on single nozzle printers.

Use 0.20mm resolution, and 0.28mm first layer height. I assume your printer is capable of 0.2mm accuracy. Afterwards, just slide the result over the button.
