I’ve been messing around with the Udoo recently and I noticed there weren’t any cases available. I just 3D printed my own (this one) but if you need one I’m happy to print them for $25 shipped, $40 for overseas orders. They take a little while to print, which makes them a bit more expensive than I’d like but let me know if you need one. I can print them in a few colors including black, green, and red. These print best in PLA and my machine has the occasional problem of letting the plastic bend up slightly at the corners, but it doesn’t effect the case structurally. If I have enough interest I may just injection-mold these.
I have models for the Udoo Dual and Udoo Quad and have had many happy customers.
