(Update: After over a month of use the male threads on the base have stretched a bit allowing the shower head to be turned a bit too far. I have added a new piece with the female threads rotated 15 degrees to compensate for this and it has lined up perfectly for me while using the same old base piece secured to the wall.)
Simple mount for a handheld shower head with adjustability that can be locked in place and secured with a knurled nut.
I designed this to fit around a 14.2mm shower hose with a tapered nut that is roughly 24.55mm at the widest, 20.75 at the narrowest, and 40mm long.
The in-slicer pictures show the orientation I had the best results with printing but ymmv. I printed in standard PLA at .16 layer height and 20% infill and standard cura ender 5 settings with tree supports.
I split the base into 2 pieces so I would advise anyone considering this to print the smaller pieces first and make sure they fit before printing the larger piece. The gears are a tight fit and may require some manipulation, but mine loosened up very nicely.
This was mounted to the wall with the thick 3m double sided tape (heat gun used to heat the wall and tape for best adhesion) and 2 screws.
