bottle rocket hand launcher

thingiverse

With this print, you can launch bottle rockets from your hand with ease. My large hands fit comfortably inside it, so there's no reason why yours won't. The tubes are 13 millimeters in diameter and have had 9 millimeters removed, making it suitable for almost all bottle rockets to fit snugly. I advise against inserting the firing mechanism into the tube as it may get stuck. When launching a rocket, hold the launcher at your side rather than in front of your face, where the fuse could potentially fire back towards you. The rear section of this design does provide protection for your arm, but be cautious nonetheless.
