This is a sliding indicator for your dishwasher that shows if it's clean or dirty. It comes in a 6 by 2 mm magnet version and a no magnet version. If you have a different type of magnet, you can easily edit the values of the spreadsheet in the freecad file. All pieces just snap together. If you are using the magnets you will need eight 6 by 2 millimeter cylindrical magnets, you will also need to add a print pause in the slicer.
