Printing In Progress Sign

#MakerMay What's the best way to caution someone when a 3D printer is running? You print a sign for it. Here is a sign that indicates a 3D print in progress. Its a triangular caution sign designed by me in Solidworks. .sldprt and .stl files available.

Ideal way to print this would be to change filaments as shown in attached pics. (first yellow then black.)

Hope you like this design :) **Link to Caution Hot Sign: **https://social.thangs.com/m/61691
