Honestly who hasn’t dreamed of launching your own red or blue shells as seen on Nintendo’s MarioKart franchise. The good folks at Maker Bot Industries in Brooklyn, NY created the affordable 3D printer that made this whole thing possible. With the available instructions and template, anyone with a few grand to invest in a Maker Bot’s 3D Printer and the know-how to solder the donor RC parts, you too can live out your IRL MarioKart dreams.
For those of us who can’t drop a few stacks on a 3D printer, there’s always this video.
