Apparently I needed a sign for the office toilet, so here we are. Many thanks to the original creator on Printables for the F3D file containing the main element of the sign - 2 people and a bat! Those were copied and the warning sign redesigned around that.
Note: model requires AMS for a 3 colour print, the colour change is flush on the build plate. If alternatives for those without an AMS are required shout in the comments.
Included 3mf file prints at 0.20 with 15% infil and is pre-painted with the model facing down on the build plate for that super smooth, or textured finish as you prefer to print. I printed on the lightyear g10 and it came out brilliantly.
Let the print cool on the build plate to prevent warping and afix to the wall with double sided tape.
STL attached if you want to paint yourself.
