I made the files a bit bigger to fit my Galaxy S6 with a cellularline "Hammer" case.
In addition, I turned the lower holder since the one that was available in downloads tilted sideways (I needed it back and forth...). But I cannot upload the STL files. Should have done a mashup or something. Basically I just cut the rod of the lower holder with Netfabb and then rotated it 90 degs.
I also suggest printing the lower holder upside down, but then you will need a screw in order to remove the support (see picture)
