The design was intended for a strong and light attachment that doesn’t weigh you down while you’re moving, and keeps your hands free when you need them. It’s also been updated many times with different settings to improve comfort, draw speed, and strength.

You read that right, this 3D printed Nerf gun attachment fits to the end of darts and other ammo with a string to form a working grappling hook.

With enough practice and some keen aiming, you’ll be able to fire at and pull objects around using your Nerf gun, and may even be able to take the weapon straight from your opponent’s hands, or just rescue those potato chips you forgot to bring to the sofa.

The original design has been known to be somewhat fragile, so if it breaks on you then you can still find an updated and stronger version instead, with upgraded 3D printed parts. Though it is also worth considering stronger or thicker materials, just make sure it’s light enough to still fire and you can grapple away while Nerfing!

The design was tested multiple times by the creator, and makes 3D printed Stryfe modifications much simpler due to its malleable and multi-purpose design.

The 3D printed barrel doubles the length of the original, making the Nerf gun look cooler and fire further.
