The Red Rocket is the humorous name youtube user "TAOFLEDERMAUS" Jeff Heeszel ^[1] gave to a 3D printed %60 solid shotgun projectile, or slug. It was printed using the Solidoodle 3 3-D printer.^[2] The slug was created by an American named Tony Griffy.^{[3] [4]}

The printer used to create the bullet retails around $800 as of September 2014, and it took the printer about an hour to produce the slug.^[2] ABS thermoplastic material was used in the production of the slug.^[2] During testing, the slug penetrated a 2×12 piece of pine wood, and created a hole in a wire reel.^[2]
