My dishwasher constantly gets opened mid cycle since my household is bonkers so I made this hanger sign and it worked ok until I spray painted the DO NOT OPEN side red, then it worked awesome.

I added 2 pieces of furniture pads into the handle section, the ones you put on the feet so that the chairs and tables don't scratch the floor when you slide them. This helped steady the sign in place when in use.

I built this in tinkercad.

I used .6 layer height with a .8 nozzle. If you use a different size, results may vary.
