very funny warning sign! thank you for it!
Printed the sign at 50% size, and 75% size for thickness, to have enough layers to print in 3 colors.
Since I currently do not own red PLA, I just used the silver one to test this print.
It's fun to see the people mimic when reading the sign and suddenly understand what the actual danger is! :-)
white, silver, black
printed with three colors, by pausing the printer to change filament.
