Really Simple Dishwasher Sign

Dishwasher sign if your dishwasher happens to have a round handle. You have to measure the diameter of the handle (the default value of 12.25 is for a 13 mm). The diameter you enter has to be smaller for it to snap on.

If you're going with the double flag version you have to check if it fits between the handle and the dishwasher wall (the gap should be large enough for this and the thickness combined with some room to spare).

Or you can have a single flag.

You can have embossed signs (cross and checkmark), but I've found that colors work much better, you can see them clearly.

Generally you don't need supports, unless the emboss depth is large.

I highly recommend skipping the embossed symbols: paint it or stick pieces of red and green tape to it. Have only one flag, and you can have a large flag, because it won't have to fit between the handle and the wall.
