Spent a lot of time on designing that enclosure but then realized I'm going to have to go pro. What I mean by that is I will need to send this off for fancy 3D printing. I did cost a pretty penny but hey worth it, ordered 3 because stuff happens. Got it done in HP Multi Jet Fusion, HP PA12 Nylon White, Vapor Smoothed. Came in not so smooth. Oh well more post processing i suppose... yay for me!

Here it is after priming and painting.
