Door Open/Closed Sign
thingiverse
I made this for my wife's office. She works in a cubical and people are always stopping by and interupting her work. She may not have a door but now people can know when her 'door' is closed and when she is free to chat! This object was made in Tinkercad. Edit it online https://www.tinkercad.com/things/iJwS4uGyrZt
