Hatsune Miku Light-up Headpiece (Commercial use permitted with author attribution)

This is a Hatsune Miku light-up headpiece powered by button batteries, weighing less than 50 grams, making it very lightweight. With just two lithium batteries, it can light up for over 15 hours, enough for a full day at an anime convention, though the brightness will decrease over time. A pair can be made for a cost of approximately 11 RMB. Additionally, I welcome everyone to create and sell their own products; for commercial use, I have no restrictions as long as the author is credited. Materials needed include a 2032 button battery holder, laser tape for decorating the pink areas of the headpiece (you can use different colored tapes and various printing materials to achieve different styles of headpieces), and a 3mm pink COB LED strip, with a recommended 400-light 5V model. Currently, there is light leakage on the sides of this model, so I have created another version with transparent material printed on the sides, which will be released here after some minor issues are fixed.
