Firecracker Keychain

Guys, we made a creative design for the New Year's Eve party! The small firecracker is very New Year's atmosphere, as our printer doesn't have AMS, so the text is replaced by a sticker, the text on it means happiness, become rich, and there is an LED inside, perfect for use as a keychain.The model also comes with 1x 5.8*5.8mm self-locking button, 3x AG3 button batteries, 1x 3mm LED, and 1x 500 ohm resistor. If you have larger button batteries and need to change the size, please adjust the diameters of the top, middle and bottom parts by yourself and adjust the tolerance according to your printer. If your printer has AMS, you can also print out the text in the same colour supplies as the top and bottom.
