At 3DSourced we’ve covered everything 3D printing and 3D since 2017.

Household names in toys are easy to think of in droves, but few come to mind quite as quickly Hasbro’s Nerf line of projectile toys.

Child development expert Garry L. Landreth once said that toys are children’s words, and play is their language. Toys have been a universal method of self-expression for centuries, and this expression has been personalized even more with 3D printing.

Thanks to their plastic frames and modifiable builds, 3D printed Nerf guns and Nerf gun mods are found everywhere, breathing new life into an old favorite and introducing some very cool additions.

In this article, we’ll look at some of the coolest and most interesting 3D Printed Nerf Gun mods and projects from designers devoted to making play time a lot more fun.

A true passion project in the growing art of 3D printed Nerf Guns, the LF1 Nerf dart launcher should be the first stop for anyone who seeks the satisfaction of wielding a Nerf gun they’ve made themselves.

This fully 3D printed Nerf gun requires some extra attention both during and after printing, as well as some extra parts that need to be sourced elsewhere. The designer has set out fully detailed instructions and pictures to ensure the build goes as smoothly as possible, and the end result is nothing less than your own homemade 3D printed Nerf gun.
