Going a step further, imagine hardware manufacturers noticing specific defects, then publishing new updated CAD files for a part that lasts better than the last, for customers who already have 3D printers to print their own upgrades/"patches".
That can work, but 3d printing doesn't in general make for strong parts (layers). Most of the time you want some form of molding or CNC subtractive machining (either plastic of metal) - while some hobbyists have this, 3d printing is far more common. (and often easier)
