foam dart blaster

choose a launch mechanism to make your own foam dart blaster. please do NOT shoot your friends

build instructions

finding a design

for my example, i watched mark rober's "world's smallest nerf gun" video, where he designed and 3d-printed a nerf gun in one piece. i thought this was cool, because it's not easy to launch a projectile when the whole blaster is made out of stiff plastic. his design works by removing some material, allowing the plastic to be bent, so it can store and release energy.

modifying it (optional but recommended)

my fingers aren't tiny enough to pull the trigger on his original design, nor do i have a nice enough 3d printer. so i scaled up his design to make the world's most medium-sized nerf gun instead.

building it

lucky me, this step was pretty simple. i just clicked print and the entire blaster was finished. it came with darts too. i immediately began shooting (non-living) things (in a safe and controlled manner).

your task

watch a youtube video about making a foam dart blaster or nerf gun. in the google form, submit a sketch of the design, the bill of materials you need, and step-by-step instructions for when you're going to build it.
