This is a redesign of MiddleFingerBoss' Sliding clean dirty sign. All parts were redesigned to simplify the assembly process. I printed these 100% infill cause I love wasting filament, but it makes it so you can sand the surface and polish it a little easier. I bought a bag of suction cups off amazon for attaching this to the dishwasher. Also, I acetone welded the stopper and the suction cup holders to the back of the letter plate, but I'm sure any other glue will work great. The plate sides awesome into the letter plate holder, but you may have to sand a little bit on the edges to get it to side effortlessly.
Thanks for looking.
Acetone smoothed and sanded.
