Fireshot- Bow and Arrow

thingiverse

This little bow and arrow was crafted during my free time. Feel at liberty to amplify its size, but refrain from scaling it down, as this will compromise the dimensional precision. UPDATES: 1.1 - Modified Ammo design to enhance its range Measured Accuracy (10 trials Conducted) Version 1: 1:1 Scale Average Distance: 0.89 Meters Highest Distance: 2.37 Meters Estimated Force: 6 Newtons Version 1.1: Average Distance: 3.02 Meters Highest Distance: 6.5+ Meters (Exceeded measurable limits) Estimated Force: 6 Newtons To Fire: Version 1: Insert the back end of the ammo through the bow and into the backing. Draw back on the backing until the ammo's tip is nearly through the bow. Place your hands on the tips of the bow, holding the backing in place. Release the backing, allowing the ammo to fire. Use an angle greater than 7 degrees relative to the ground. Version 1.1: Insert the back end of the ammo through the bow. Draw the backing to the desired amount of force needed to shoot (the further back you draw on the backing, the farther it will go). Release and watch as the projectile fires out. Note: This is not a weapon. I assume no responsibility for any consequences resulting from its use. Do not point this at anyone or anything. Print Settings Printer: M3D Micro Rafts: Doesn't Matter Supports: No Resolution: 300 Microns Infill: 40-80% Notes: Do not scale down this model, but feel free to scale it up. I advise against scaling it down as it will render the arrow useless and compromise its dimensional accuracy. This model contains its own ammo, but can be scaled up to accommodate other objects (e.g., a slightly larger scale can make it shoot a pencil). Post-Printing Instructions It's just finished printing, so remove all components. 1) Bow Frame (The curved part that resembles a bow) 2) Backing (Has a circular hole in the front and a rectangular hole in the back) 3) Ammo Take the bow frame and a rubber band. Insert one end of the rubber band into the little L bracket at one end. Secure it with hot or super glue, waiting a few minutes for it to dry. Then, insert the other end of the rubber band into the other L-Bracket on the opposite side. Secure it with hot or super glue, waiting another few minutes for it to dry. Place the backing's front side (the side with the circular hole) on top of the bow's center hole. Next, take the elastic's sides and insert them into the backing's holes. Glue them down using hot or super glue. After a few minutes, it should be ready!
