Simple "wet floor" style sign to mark where your cat vomitted. Easy multi-color print. Added 75% and 50% scaled models with the tolerance in the hinge kept the same.

STLs can be split to parts in your slicer and changed color. 

For the flush model part 7 and 32 were the ones I needed to make yellow, all the rest were black. Only needs to change filament twice so you can easily do it manually if you don't have an MMU/AMS. 

For the recessed model part 12 and 13 were the ones I needed to make black, all the rest were yellow. There are 3 filament changes to get good coverage since the graphic is unsupported, still easy to do manually.

Remix: Upscaled the original model, thickened the hinge for strength, added tab for hinge tension, changed words and graphic on sign. Made models multi-part for easy multi-color printing. Made one version with flush face.
