Do not touch - Warning Sign - 3 Colour Version
You can print this in 1, 2 or 3 colours. Just put in a filament change in your favorite slicer program at the right layer.
The size is also adjustable in your slicer program.
Note: If you slice it very small (about 40mm wide and smaller) the letters could get a little strange but its not that worse at all. In any case if you print it this small you should raise the height to 1,5 to 2mm to get enough layers for one or two colour changes.
100% Infill
PLA or PETG works best.
