Okay I heard about this concept a few times but didn't know it was actually the real deal.
Apparently, you can 3d print (Custom make) your own video game accessories and tons of other stuff.http://www.forbes.com/sites/louiscolumbus/2016/04/24/7-ways-3d-printing-is-making-manufacturing-more-competitive/
Like figures, weapons and even parts of your console.
They even have files all over the place like this old school cartridge holder (For the genesis / Mega drive).https://pinshape.com/items/18298-3d-printed-sega-sonic-cartridge-sleeves
Has anyone heard of this? Love to make my favorite action figures (Robert from Art of Fighting - OH YEAH!).
