Minecraft LED Sword

thingiverse

there are some minecraft swords on thingiverse... but i did not find any with LED ;-) this is my first selfmade 3D object - please let me know how i can make things better :-) I split this sword into 4 parts because my printer can only print 20x20x20 and i need different colors for the blade and for the handle. for the code i simply used the button cycler demo: https://github.com/adafruit/Adafruit_NeoPixel/blob/master/examples/buttoncycler/buttoncycler.ino for the electronical parts i used: - mini Slide switch - main body: 10x5x5 mm complete: 19x15x6 - Tact Button Schalter 6x6x4,3mm 6 * 6 * 4,3mm 4 Pin Micro PCB SMD SMT Momentan Tactile Tact Push Button Schalter 4 Pin DIP - WeMos D1 Mini Battery-Shield - WeMos D1 Mini - but any other arduino should work - Accu: 3.7V 800mAh LiPo Akku 25C 1S - M3 screws (5 or 6mm long) - threaded insert M3 - standard WS2812B LED strip (for me 17 LEDs fits best)
