This is a design I made to house our enterprise project. We needed a case that was light and as compact as possible. We are also designing the circuity and needed to be able to easily modify the the case to fit with our components and buttons. The case is easily scalable and worked well for our needs.
The cost of a simlar sized uncustomized pack is about $7 and I would estimate that having the case manfactured anywhere would be at least $200. The ability to quickly change the design and print a new prototype alone made this project valuable to our enterprise team.
