The file 'Wall Mount Cell Phone Holder 3D Printer Model' is (stl) file type, size is 6.8KB.
I made this small shelf to hold most modern size cell phones, it hold my iPhone 6 in a lifeproof fre power case with a little room to spare. Screw holes are countersinked and sized to hold a standard course drywall screw flush with the plate. This ended up being incredibly sturdy, I printed it with a 15% infill, .2mm layers, with three layer top and bottom, and 2 layer sides, with PLA and i couldn't break or bend the shelf at all even putting almost my full weight on it. Probably a little overkill, but it does the job nicely.
I had no problems with the very long bridges required to print the lip on the top of the print, I did have to cut out a few strands of PLA that were a touch droopy but you can't see them once its mounted as it faces the wall.
Printed on a replicator 2 using inland PLA, and simplify 3D 3.0 as a slicer.
If your phone is larger than 3.5"x 6.5" feel free to modify the design to fit.
