People would still knock on the door even though I had a "No Soliciting" sign up. I would open the door and point at the sign, and they would say "but I'm not soliciting - now let me tell you about a new solar installation". My real problem was people bothering me by knocking, so this one gets to the heart of the issue. Haven't had any knockers yet.
The sign in the photo is printed in PLA:
Scaled 155% on all axes
0.4mm nozzle
0.2mm layer height
15% gyroid infill
2 walls
3 top layers
Pause at start of layer 17 (3.4mm) - Print with black first, switch to yellow during the pause.
I have provided two versions, one with a rim and one without.
