The case does fit very tightly I´m actually having problems to get it off at the moment (you might want to print it a little bit bigger than the exact size) Thickness 1,5mm Printing size and orientation might not be correct the depth should be correct (phone + 1mm overlapping on top to get it in +1,5mm case) The other sides are 3mm because the are 2 sides covered by the case + the size of the phone I hope you like it I´m open for any ideas If anyone needs the blender file I will upload it.
