Yeah, the enclosure has gone through more iterations. It’s a typical struggle for an electronics product: The struggles of engineering the hardware and software complete, then the impossibilities of the enclosure begin.

Yes, a single enclosure can be built, but it’d be a few hundred dollars! To make it cheap, you have to order 10,000 or 100,000 of them, with commensurate costs. And this is so when you don’t even know if anyone will purchase your product!
