Though heavily inspired this is not a remix of "LED Zelda Master Sword with Sounds" by Adafruit, but designed from scratch from the source https://gallery.autodesk.com/fusion360/projects/master-sword--sheath-from-legend-of-zelda

Main differences from Adafruit version :
- smaller parts to fit 220*220 print beds
- no broken geometry
- sturdier handle (larger walls and key insert in the guard)
There are two versions of the handle :
- a classic version, similar to Adafruit's, split in half like the other parts, with a hole on the extremity of the pommel to add any kind of USB or DC jack
- a solid version designed for a USB-C port and the pommel acting as a screw cap
Electronics I used :
- 2x80cm WS2812 LEDs strip (2x48 LEDs)
- 18560 battery with protection circuit
- TP4056 LiPo charger **
- MT3608 Step Up Converter
- Arduino Pro Micro
- ADXL345 Accelerometer
- USB-C female connector
- 11x5mm mini switch
You could also use Adafruit's Feather M0 + Prop-Maker to replace the power circuit + controller + accelerometer.
** the standard TP4056 module found on Amazon or AliExpress does not support load sharing, meaning you MUST NOT charge the battery while the lights are on. You can find here https://www.best-microcontroller-projects.com/tp4056-page2.html a guide to add load sharing capabilities with a P-MOSFET a Schottky diode and resistor.
(The provided wiring diagram does not contains the load sharing part)
Print settings :
- 0.2mm layer height
- 2 walls (3 for the Handle)
- 10% gyroid infill
- 5mm brim
- no support
