Had this idea for a showerhead with an open handle. Designed in FreeCAD, to learn the application.

The bold can print it in one go, but it's easier to print each part by itself and jus glue together with CA afterwards. Print settings I used with PLA:

Connector with 0.1mm layer height, no support. ~1h Shaft: 0.2mm layer height, support only touching base. ~5h Head: 0.15 layer height, support only toucing base. ~8h

The print isn't 100% watertight, so it's leaking a bit through the walls. For final product it must be coated with something.

Feel free to remix. :-)
