Just a little sign to indicate 2 states of 2 things. I use it to show whether each of my cats is inside or outside. You could use it for indicating whether the dishwasher is clean or dirty, etc.

The included PrusaSlicer project has sample embossed text for you to edit

• I don't have a multi-material setup, so I just use a couple of filament changes for color contrast
• This has print-in-place hinges with no overhangs over 45deg, so no supports are needed
• I stuck it to the wall with a command strip
• There is a “right-side-up” direction: they should click into place when flipped up so they don't fall down

“increased clearance” files have 0.5mm total slop in the print-in-place hinges instead of the normal 0.25mm in case that is required for your printer.
