The Octo Shot blaster is a homemade technology project which functions in a similar way to commercial Nerf products, however is far more powerful. It uses a larger plunger volume, stronger spring and overall more heavy duty components. Many of these pieces are 3D printed; either in ABS or PLA, however the plunger rod, plunger tube, barrel and other certain pieces are made from strong materials such a aluminium or injection moulded PVC. Finally, this blaster fires darts made from foam insulating material at an estimated 75 m/s initial velocity.
