shower head mount, rotatable and clampable

I'm really pleased to have been able to design an improvement for a cheap shower mount that doesn't screw loose after some time. (Bought in a german hardware store. Maybe you can utilize the adapter part or maybe the whole thing just serves as an inspiration for you to adjust to your shower head mount. Feel free to alter.)

So, this is a kind of adapter for a store-bought shower head mount that allows you to change the shower head angle, but still clamps quite tight (so the damn shower head doesn't fall down).

The secret is: I glued a M8x35mm with a hexagon socket into the "thread clamp". I had an older design with a printed thread, but no matter how big the infill or line density, the torsion broke the thread clamp every time.
