This case is designed to hold the ZTE Speed Smartphone in a way that does not block it's camera, while also holding the Micro-USB in firmly. It also has a Tetrix hole pattern on the back for easy attachment to any Tetrix parts. The front of the case is open, allowing for easy access to the touchscreen without needing to remove it.
A high resolution may be needed to keep the USB holder strong. In this prototype print (shown in the images) we used a draft print mode, which made the USB holder a bit spotty.
Installation of this phone case is simple -- Use standard Tetrix screws and Tetrix parts to mount. Slide the phone in (It may be a tight fit, that is a good thing). Plug the micro-USB cord into the phone.
