This is a repair designed by me for a Roca showerhead.
The support of the shower head interior broke, making it to fall with the water pressure.
I believe it should not be a very common issue :) !
Made this part in ASA, but other materials should work too.

The bolt and the broken piece should be removed.
The showerhead internals must be put in place.
The 3d printed goes in the center bolted with the original screw.
