This is a 3d model for a device that goes on your wrist and shoots. Depending on the spring, it can shoot up to 50 feet! The Zip file contains all the STL files needed to print this, and it also contains a video of it in action. Look closely, because it shoots fast! NOTE: the 3d printed strap is not included in the folder! I made a connecter for a strap so that you can use any strap of your own! Also, you will need a spring is required for this, and a pen spring may work if it is wide enough but it will not create a lot of force.
