I still wonder why open hardware hasn't taken over the consumer electronics market yet. Hackability/upgradability is a feature I would pay for... ah wait! these things (Pi, 3D printing) are even cheaper than many closed designs.

The problem is that people and companies are still not okay with the idea of paying for R&D of open source, especially when it is not a direct investment - i.e, they pay for FOSS only when it is going to make or save them money elsewhere.

Open source consumer electronics does neither. It is at best a hobby and a very expensive one at that. Take a look at /r/mechanical keyboards or /r/headphones and you will see.

But I am with you. I would love to work on a drop.com equivalent that would focus only on curating and aggregating open source projects focused on consumer electronics.

I think it's hard to get funding for that business model.

Really, the chances of getting funded go way up when you have patents, exclusivity, a monopoly, etc.

Because it's easy to commodotise it. If all the designs are open then the race is to who can manufacture it better but there's a technological limit to that and the return on investment is quite low. What would be a company's market differentiator in this? Quality of construction is easily achievable nowadays, price will be low (as the market is very price-sensitive, who will be buying US$ 100 cases for their Pis?), there is not much incentive to participate in it, even more as the market is quite niche.

Maybe a company doing the packaging and selling of open-source hardware as whole product, much like as Mutable Instruments did with modular synthesizers, could work but then you aren't simply making cases anymore.

Chinese companies don't seem to mind doing this. The answer to thread OPs question is that all the stuff they want is sold by Chinese manufacturers.

For (1), I made https://callanbryant.co.uk/blog/universal-wall-mounted-touch... which works pretty well supporting a Pi3 + (generic) PoE adaptor.

I doubt there would be a viable market for commercial production like that, but I've seen several 3D-print-at-home options for custom cases for Pis and similar.

Lots of individuals make them. They design and 3d print them with their home printers.
