The guide details required components, electrical wiring reference via a circuit diagram, and practical assembly steps such as pressing fit parts, mounting a slide switch and TPS board, connecting the nOOds and LiPo battery, and joining blade and handle halves. It emphasizes reinforcement of 3D printed sections with steel machine screws for strength and durability.","Rumi Sword-KPop Demon Hunters  \nCreated by Ruiz Brothers  \n[https://learn.adafruit.com/rumi-sword](https://learn.adafruit.com/rumi-sword)  \nLast updated on 2025-11-03 09:51:37 AM EST  \n©Adafruit Industries Page 1 of 16  \nTable of Contents  \nOverview 3  \n\n| • Parts\u003Cbr>• 2x of Noods\u003Cbr>Circuit Diagram | 7 |\n| --- | --- |\n| • Adafruit Library for Fritzing\u003Cbr>• nOOd gap close\u003Cbr>3D Print | 8 |\n| • 3D Printed Parts\u003Cbr>• Filament Change Layers\u003Cbr>Assemble | 11 |\n\n• Join blade parts  \n• Press fit nOOd  \n• Mount Slide Switch  \n• Mount TPS board  \n• Attach blade to hilt  \n• Hilt slit  \n• Connect nOOd  \n• Mount lipo battery  \n• Connect battery  \n• Join handle and blade halves  \n©Adafruit Industries Page 2 of 16  \nOverview  \nSeal the Honmoon with Rumi's sword from KPop Demon Hunters!  \nPowered by the Adafruit TPS61169 Constant Current Boost Converter for LEDs!  \nTwo Pink LED nOOds illuminate the blade and handle to create a bright cosplay prop!  \nWe designed the sword with steel machinescrews to reinforce the 3D printed parts so it's strong and durable, just like the demon hunters.  \nNoods LEDs are often seen in 'Edison-like'LED bulbs, shaped into hearts or stars or just wound around to create a fun or warm lighting effect.
