I have a Miele dish washer using unrefillable disks with cleaning powder distribution.
After having seen https://mcuoneclipse.com/2022/06/04/refilling-the-non-refillable-miele-autodos-dishwasher-automatic-detergent-dispensing-disks/
I decided to give it a try. This model is a plug to be print in TPU (I used Polymaker Polyflex)
The model and the 3mf are available for you to adapt at your taste.
It is complementary to the refill plug https://www.printables.com/model/283483-miele-dish-washer-cartridge-plug
Happy savings
