I've been watching a lot of AvE[1] lately, and his BOLTR series features him breaking down hardware and talking about the manufacturing.
While Teenage Engineering wank is definitely not his category of analysis, it's probably not far off, considering he highlighted how spotty the Dyson product line is. I'd love to see him disassemble something like the OP-1.
Edit: Missing link reference.

Apparently, OP-1s use CNC'd solid block aluminum machining![2]
