I know there are some other guys doing a similar thing, but when I started my second GB zero build 2 weeks ago, I decided to print my own case. I looked around and didn't find any (finished) GB zero case with the original measures of the GB. So I decided to give CAD a try myself.
I used OpenScad to create the 3D model and took the measures from an 'original' chinese case and changed it to my needs and according my skills as I only started using CAD 2 weeks ago.
Below you can find the results, at least the top part of the case. Tht buttom will follow soon.
I played around quite a lot and printed several loops. In the end I had to sacrifice the original look to make it printable (mainly the 'sloped' parts around the buttons didn't really work out).
Additionally to the case I'm aiming to make the build as clean as possible. Therefore I made something like a frame for the screen. I added a bed for the screen control board and a bed for the teensy.
On top I will cover the lower part and make similar 'beds' for the amplifier, power strip etc.
The Pi itself will be screwed to the screen frame. There is also a small frame for the audiojack. So far the design seems to work for me. Still a lot of improvements to implement though.
So far I have been using PLA, which gives a quite nice surface when printed on glass. I will try to spray paint the case and see how the surface will look like.
I also might want to try ABS and put it above some acetone so see how that would like.
Any thoughts on that? Any recommondations?

So I worked on the case for quite a while now and and after lots of fine tuning and countless prints I am almost done.
I'm really happy with the result. I designed it in a way so I almost won't need any hot glue. It's tailor made to the parts that I am using, but it should be fairly easy to adjust it to whatever other parts I might use for future builds.
Maybe I will implement some status LEDs in the empty catridge. Let's see.
I tried different techniques to give the case a nice finish and I decided to sand paper it, refine it with putty and spray paint it. The pictures show the almost final case before all the refinement. I will only do that, when I'm sure everything is how I want it to be.
After I finished the GBZ up, I will share my STL files with you guys
