I'm skeptical. For things like appliances most manufacturers already sell replacement parts for cheaper than you could "print" them yourself, without the problems associated with printing it yourself. For things like consumer level electronics, the manufacturers could sell replacement parts, but they'd prefer people replace the entire item. If the camera manufacturer won't sell a replacement flap, it's unlikely they'll give out the original CAD files for people to print their own.
