Guardian Sword with NeoPixel LEDs 3D print model

This is the Guardian Sword from Zelda, Breath of the Wild. It’s fully 3D Printed and has a ton of NeoPixel LEDs. This thing is super bright and looks so awesome!

The blade is designed in Fusion 360 using reference images from the game. Its designed to be 3D printed in several pieces and connected together using screws.

The sword is pretty massive, it’s about 34in in length and has over 90 NeoPixels.Once I got it in the game, the first thing I thought was, wow this is so cool, I have to make it!This project showcases a high-detail 3D model of a futuristic energy sword, developed in Blender, and its real-world LED-lit replica designed for cosplay, display, or fan builds.

3D Model (First Image)Crafted in Blender with precision mechanical elements, layered armor plating, and modular assembly for flexibility.Features include futuristic mechanical parts, symmetrical geometry, embedded sockets, and complex edgework for sci-fi aesthetics.Ideal for game engines, cinematic rendering, or 3D printing for physical prototyping.

Modeled with functionality in mind—visible screws, cutouts, and framing structure aid in real-world manufacturability or animation rigging.

LED Replica (Second Image)Realized as a fully functional LED sword prop, glowing blue along the blade and red along the hilt.Designed for immersive cosplay, YouTube builds, or tech-art installations.Blade lighting mimics energy channels found in futuristic or cyberpunk worlds.As seen worn across the back like a hero weapon, suggesting its use in character-driven content, gaming cosplay, or themed events.
