Tired of always being asked “What are you doing in there?!” Well no more. Let everyone that questions you know what's going down in there. Have a spouse that needs to get ready for work and you don't want them to walk into a restroom fumigated with your bodily toxins? Without uttering a word they'll know whether you're going to take one minute, or twenty and know that's it safe to enter the premises without fear of being knocked unconscious by a gaseous miasma.

I used double sided velcro tape, but i put holes in it incase anyone wanted to use nails. This model is a great use case for the Makerlab, "Make your own sign". The sign is easily replaceable, the clearance is 165x52 / 2.5mm thickness so anything slightly smaller should fit if you decide to make your own.

The print profiles are already set and ready to print, the supports have 1 layer separating from the base model for an easy pull of with pliers, you might have some smaller pieces remaining after pull off but they easily scrape off with the pliers and are also covered by the signs after assembly.
I made the sign using Hueforge but its just black and white for color. You don't have to use the same but it might not look exactly like mine if you dont use the same brand and type, which i used Bambulab Tough Black and Matte Ivory White. Careful with the pull off, the black prints out super thin comparatively to the white, that's just how the software works.
