I wanted a way to check this without printing the whole housing. I also wanted to check how well my phone would fit to the housing. So, I produced a couple of sections through the main housing (with OpenSCAD). The first is a 2mm thick section of the curve which fits to the head, the second is a 1mm thick section of the front face which fits to the phone. On my printer they take around 20 minutes each to print, rather than 5 hours for the whole housing.No special instructions for printing. These are meant to print quickly, so you can decide if you want to print the whole housing or not. One the phone face section I've added spars to the gaps to make a one-piece model. These spars are slightly raised so they can be distinguished from the main section.
