I started off designing the phone case by getting the dimensions for my phone. Thankfully it wasn't one of those "ergonomically" shaped phones, so the phone was basically a rectangle with rounded corners. After taking down the dimensions I opened up SolidWorks and started playing around with different concepts. Eventually I came to this design.
(This render came after making the case. I got lazy and used polycarbonate instead of an aluminum ring as I had originally Intended)
This new design gave me the option to do all of the parts with single sided machining and minimal material removal. Both are things I strongly prefer when producing any part. Hopefully the case will be a quick one day project.
