When I get a new toy (electronic device), I usually like to trick it out with a protective case. It's cool and all if there are cases available, I'll just look at the designs available and choose one I like. However, sometimes there aren't any cases available.
For instance, I got an Evo 3D. I wanted an extended battery to go with it. The only one with a case available is by Sedio. It's super expensive, and I don't like the design. I went about finding a cheaper one; of course, the cheaper extended batteries don't have cases.
Since, I have a FDM printer lying around, I went about creating a custom case for it.
This instructable will teach you how to model the case to fit the phone/any device.
