These signs were originally inspired by a visit by someone trying to get me to switch my propane company, thus they started with the No Soliciting sign, then I made up the Do Not Disturb and No Trespassing. Living in an Apartment, I couldn't just slap a regular sign on my door without damaging their door. So these were designed with the ability to zip tie them to the door knocker, or you could hang them on the door knob, and even daisy chain them together. Of course, you can also just screw them in if you don't mind the damage. The No Trespassing would also be nice to post on the door of a gate. I would print them in ABS since you want them to survive hot days. You could pause on height at 2 mm and change filament colors rather than painting them like I did.
