[24/06/2019] Update: the pin that holds the showerhead, broke off on my print. To fix this problem, I drilled a 4mm hole through the pin and the mount, after which I inserted an M4 bolt for strength. If you are concerned about the strength of this part, you can print the reinforced .STL file, which includes a 4mm hole for an M4 bolt to be inserted into.
I modelled this showerhead extender, because my showerhead was too close to the wall. The part is printed with 100% infill for high strength and has been designed in such a way that you don't need support material. If you want to bottom side of this extender to be a bit cleaner though, you could turn support on.
