Do Not Touch Signs

thingiverse

I am a kindergarten teacher. One of my favorite things to do is teach my kiddos how a 3D printer works. I even help them design something simple in Tinkercad and then we print it. It is a lot of fun! My only concern is that my little impulsive puppies will touch my printer while it is working. I am not really scared that they will burn themselves. The hot end is tucked away under my fan ducting and they would really have work to get up under there. Mostly, I do not want their dirty little fingers on my print bed. :) I made these signs to help keep them from touching the printer. I designed them in Tinkercad. I added a little channel on the bottom of the sign to help it release from the print bed. A little squirt of 50/50 alcohol-water solution helps these flat prints release. The channel allows the liquid to get under the print a bit better. I printed them in white and then used some sharpie to add color. I put a couple magnets on the Do Not Touch sign so it is movable. The Hot sign is glued to my fan cover.
