A little gadget that attaches to the washing machine door and indicates the state of the machine. Especially useful for public places. It has a strong detent that is achieved by a heavy spring and ball bearing.
- Pyramid indicator (printed)
- Detent insert (printed)
- 9 mm ball bearing (haven't tried smaller sizes. Smaller might work)
- Spring, L: 10 mm, OD: 8 mm (smaller sizes might work)
Place the spring and ball in the hole inside the pyramid indicator. Align the notch in the detent insert with the ball and press in. With double sided tape attach to your washing machine. Just make sure that before attaching it to the washing machine the ball is in the detent and align one of the sides to the top, for example CLEAN side up.
I also uploaded the source SolidWorks files and the STP files. PLease feel free to make modification such as a version with no ball or spring and fully printed.

Go with thinner layer height for the pyramid to get a better result with the letters. Go with 3 or more walls and 20% or more infill for the insert as it is a high stress part.
Modified the parts to be a little bit more removable in case you need to take the insert out. Added a slot on the bottom of the insert to be able to rotate it with a flat head.
Changed CLEAN and DIRTY places with each other to have the order in clockwise (dirty, washing, clean)
