I got tired of solicitors coming around and ignoring the other no soliciting signs I had on my door. I figured if I put the sign on my doorbell, it would increase the chances of them actually seeing. After having my first kid I made this double sided to include a Do Not Ring that covers the doorbell. No more solicitors or anyone else for that matter ringing the doorbell and waking my napping child. This model was designed for a google doorbell. I printed a version with PLA glow that turned out pretty cool.
