Why would Oakley, Ray Ban, or Philippe Starck sell the design to their glasses for $3.49 when they can sell you the replacement pieces for three times more [1], or better yet sell you a replacement pair of glasses?

Because you want a poorly finished piece that takes multiple tries to print right because the extruder jams, piece warps, or a misaligned head crashes into the object turning everything into a goopy mess?
The occasional time my Replicator 1 works on the first try, it's magical. Most of the time it's an exercise in frustration.
But because of the way the market is, they have no choice in the matter.
You also might forget that $3.49 of pure profit may beat the eventual per-unit margin of even high priced replacements, which require warehousing, retailing, restocking, shipping, etc etc.
