I thought this 3D-printed Destiny fusion rifle was cool, but this thing? Next. Level.
He used three materials in total: PLA thermoplastic was used for the main body and bullet belt, while Ninjaflex filament took care of the stock, and the rail was done in carbon fibre.
It's stuff like this that really makes me want a 3D printer. Or a Star Trek replicator. Whatever's more affordable first.
