This is really well done! All the parts fit perfectly, and the drone even fits with my velcro on the top for the little strobe light. I'm actually using the bottom chamber for the strobe since I don't use the DJI charger brick at all.
My only complaint is I wish the outer shell were a bit thicker all the way around. It's super thin where the extra chamber is (under 1mm), and flexes when I touch it. The side wall next to the controller is a bit thicker (1.6mm) but also flexes. I would have loved for it to be more like 3.6mm all the way around. I might try that myself, but at nearly 24h print time it's not something I'm eager to print again!
