In this project we’re building a Prop Maker Keyblade! Keyblades are sword like weapons featured in the Kingdom Hearts video game series. This design features the Adafruit Prop-Maker FeatherWing and NeoPixel LEDs to create a unique prop with motion activated sound effects. All of the parts are 3D printed and the electronics are from Adafruit.
Assembly
I designed this to be modular so parts snap fit together. This makes it easy to take apart so it’s ready for transport. The handle and pipes connect with screw-threaded ends. The electronics are easy to get to so the battery can easily be recharged or the code updated over USB. The blade is also detachable so it's easy to break it down and put it up for storage.
NeoPixel Props
This utilizes dual extrusion to create multi-colored elements that are printed using glitter infused filament. Parts printed with transparent PLA will diffuse the LEDs to illuminate specific features throughout the build. It's designed to house all of the electronics. This design was inspired by Dave Lunar’s Iron Warrior Battle Axe - It’s a take on a space marines weapon from warhammer 40k world.
