This is a simple shower holder. It has 2 positions, for 2 different angles.
You have the Freecad file to update the dimensions if needed. To do so, you need to open the Freecad file, then the "Data" sheet. Few things can be changed like the distance between the 2 screws, the screw size... But be aware that changing the simensions may create some errors due to the chamfer that can't be implemented.
Better print with a high infill, something around 60~70%.
