Back when I got a ZUK Z2 there wasn't a single readymade case available on thingiverse, so I had to learn CAD, which I did, to create this case. It went through about 20 iterations (and about as much prints) until I got all the cutouts just the way I wanted them. Fits snugly, and extra large cutous for the usb and audio jack make sure all my cables fit just fine. I ended up sanding some of the edges and sharp lines because I've got about the cheapest printer on the market, so prints are pretty good for the money, but still a bit basic I guess.
