A remix of the amazing design from user voivoi
I modified it to fit my shower head with the peg design.

Print it as in the picture for best results, however you need to use quite a stable infill since the lever from the shower head acts directly on the peg.

UPDATE: I added another version (v3) where you can add a M3x25 screw to make the peg more stable.

With supports you could also rotate the piece and print it with the lever forces perpendicular to the layer direction.

... you need to add a M3x25 Screw. You might want to drill open the hole a few milimeters deep and then insert the screw. It will find its way and will stabilize the peg.
