3D-Printed Toy Hand Cannon Revolver
Flasutie shows off an insane toy gun that looks and works like an oversized revolver. It fires plastic projectiles using a high-voltage igniter and oxyhydrogen (HHO) gas as a propellant. Before building the main weapon, he made a single-barrel unit to test its firing system. Despite the TPU bullets being relatively soft, they could still leave a mark on unprotected skin.
