Shower head bracket on thermostatic shower faucet

Story:
I usually just get shower to save water, so I bought a thermostatic shower faucet, but after a long day it's nice to sit in the bath, but than it was hard to fill the bath with a water, because it is not a bath filler tap, so I decided to make a pracket on the shower faucet to simply fill the bath from now on. 

Features:

• It has a snap-fit connection to fit on my Grohe thermostatic valve
• No fancy cutouts on the bracket to make easier clean it in the feature

Printing instuction:

• It need an organic support
• Currently printed from PLA, but the thermostatic shower faucet can be realy hot, so maybe it need to be from PETG in the future
