Overview

Make Link's Bladesaw!

 

In this project we built the ancient bladesaw from Zelda, Breath of the Wild.

 

This fully 3d printed prop has a moving chainsaw with tons of NeoPixel LEDs

 

It has lots of detail making this one of our most intricate builds. It’s pretty massive – over 40 inches in length with over 200 neopixels.

It is a pretty fun weapon that can take down guardians by just swinging it around.

 

So we wanted to make this bladesaw look and feel like it’s straight out of game.

 

We designed the bladesaw in Fusion 360 using reference images from the game.

 

All of the parts are printed individually and secured together with hardware.

Parts

 

The Adafruit Cricket and Circuit Playground Express is a fully loaded robotics platform that will drive all of the components.

 

The PCB is secured to the built-in standoffs near the center of the bladesaw.

 

There’s so many things the Adafruit CRICKIT can do. We could take this much further with servos and sensors like the accelerometer or even capacitive touch.

3D Parts

 

The main parts were 3D printed using an Ultimaker S5.

 

Parts are dual extruded to make built-in light diffusion so details printed in translucent filament will illuminate.

 

We used Ninjaflex to create a flexible sleeve for the handle.

 

The design files are free to download and the source file is open for remixing.

 

We used glitter infused filament to give the parts a bit of texture.
