"Please Do Not Disturb" door knob/handle hanger. I needed this for working from home when I am in a meeting so my children do not disturb me. It also works for a bedroom.

Print instructions

I printed this with a 0.4mm nozzle, but a 0.6mm nozzle would work really well also. 15% infill and 3 parameters. I did a color change from black to white PLA where the lettering starts.
