Toilet paper roll holder with phone shelf, hidden screw mounting

Simple toilet paper roll holder with a phone shelf that uses a separate mounting bracket to hide the screws. 

Designed with optimal layer orientation for 3D printing to ensure the roll holder part is less likely to snap off (layer lines will run parallel to the toilet paper roll when printed in the recommended orientation). 

Requires your printer to be able to print unsupported 45-degree overhangs. Some short bridging required, but should be doable without supports on most printers. 

This is the correct orientation for the print:

To install, first screw the bracket as shown onto your wall, and the slide the holder onto it!

Mount clearances were for my printer, but you can use horizontal expansion / X-Y compensation settings in your slicer to adjust the mount size to achieve your desired friction fit.
