Been thinking a little about 3D printing, and the need for universal connectors so that all things should be augmentable by adding bits you print.
So, for instance, you could get a fridge that doesn’t have set shelves, but just space for connectors to slot on. Then you print out the exact configuration you want.
Unfortunately, I can see a future though where several ‘proprietary systems’ of connectors pop up, and we go through the physical equivalent of the media format wars, the Bluray vs HDD system of things.
Anyway, I found this slideshow from 2008, by JFTesser, of a bench system made exclusively from a universal connector style system. Lovely.
