Multiuse Door Cards (2 Versions)

My son recently became of age but I'm the pestering parent type. Since he'd like to make sure I don't walk in at the wrong time, I made this little guy to go on the front of his door. I had some leftover sticky pads from my magnets so I used those (https://amzn.to/3XBa6u3). While there are 3 pre-made ones, I put up a model of the blank so people can make their own. I decided to post this as I can see this being incredibly useful like a bathroom sign or an occupied sign. It is designed to print without supports. The middle part is to help prevent drooping from too long of a distance.Boost MeLet me know if you need me to make you your own sign. Not everyone knows CAD or Blender :)
