I needed to replace an old shower-head stand.
I could buy one, but what's the fun in that? :-)

Printed with PLA at 0.2mm.
No need for glue or supports.

Update 1: The screw cover was missing from the files. I've re-uploaded them.
Update 2: v1.1 minor change to the base and screw_cover, so that the cover will be less noticeable. Note that the pictures are of v1.0.

Assembly:

1. Connect the base part to the wall using 2 screws (up to 4mm diameter) with 22mm between them:
Note: You can connect to the wall after the assembly is done, but I find it a bit less convenient.

2. Use the screw cover to protect the crews:

3. Connect each printed screw to a screw-cap:

4. Orient and hold together the side parts around the shower-head holder part:

5. Use the printed screws to secure them together on both sides:

6. Slide them onto the base part:

7. Partially release the printed screws to adjust the angle of the shower-head holder.
