This sign was inspired by a simpsons episode. It will tell your visitors exactly what to do.. or don't.

designed in 170 x 150 mm, so it should fit on small bed printers like the A1 mini.

you don't really need a multi color system, just insert a pause command ca .75mm from the top layer and change filament.

example print was made on a Zonestar Z8PM4 Mk2 Pro with Kingroon PLA+
