As the water in my region is quite calcareous, the shower taps quickly look unattractive.
Strong cleaning agents also damage the shower heads.

As I didn't feel like going to a DIY store for this and I don't like most of the designs anyway, I designed a minimalistic shower head myself.

I have been using a shower head made of PLA for 2 months now and so far it has withstood the cleaning agents.
This part only needs support for the ½" thread.
