hazard signs for a lab (contest)

i saw these hazard signs a while ago and rememberd them bu i couldnt find the model anymore so i made some by myself with ai generation….    (there are 7 signs containing: biohazard,corrosion,enviroment,exclamation mark flame and more) they are multicolour print with a circle or square at the outside (extra print) to print in red ….  when you printed the inner of the sign simply print the outside in a colour you want an if your printer has good tollerations the will just fit when pressed tgether 

Enjoy printing ;)
