I got the idea for this from a bumper sticker that said “Safety Third”. I thought I could do better and modeled mine after the UN Class 3 flammable placard.
This can be printed easily without the MMU2 since the color changes occurs at a specific layer. I printed it in PETG, but PLA would work just fine too. On the backside are two circular indentations where you can glue two 7mm x 3.75mm magnets or bolts if you want to mount it to something.
I hope it brings a laugh to your workshop or garage. Posted makes and likes appreciated.
Print Instructions:
Parameters that I used were .2 layer height, 3 perimeters, 15% infill, 5 solid layers top/bottom.
Just add a color change in Prusa Slicer where the print transitions from the red base to the white details.
