Hi !

Dishwasher tablet form that can be prepared at home.
It does not require support. It is worth printing from a more flexible material. For example, TPU. But if you only have a harder filament, put transparent food wrapping film in it first. And then press the ingredients in.

I will also write a classic recipe:
4 tablespoons of baking soda

2 tablespoons of citric acid or tartaric acid

1 tablespoon of washing soda

2 tablespoons of salt

a few drops of essential oil (optional)

Mix the ingredients in a bowl. Add water in teaspoonfuls until it comes together. It will fizz a little, but that's okay. Add the essential oil.
Compress well in the form. After a few hours we can use it.

If you find the model useful, you can thank it with a like.

Hello !
