Shower head holder - parametric

Inclination in the uploaded version is 30 degrees - feel free to change (but be advised that rendering takes about 3 hours on my PC).
The most convenient print position seems to be lay down on the back/wall side (rotate and lay flat in Cura).
Update 4/28: version 1 w/ horizontal bottom - some bottom part cut out (because it does not hold anything).
Update 4/29: version 2 is the opposite way to make the bottom (nearly) horizontal - base expanded.
Update 5/1: version 3 has horizontal top (as much as possible).
Version 4: base and socket centered to each other (the difference from version 3 is barely visible so I did not make STL - please let me know if you need it.)
Choose whichever you like best.
