This cute mini LED neon sign is made to look like a rose. The integrated battery means you can display it anywhere. You can make it yourself with some simple ingredients. The main pieces are two 300mm 3v LED filaments: LED Filament Flexible DC3V 38mm 60mm 95mm 80mm 130mm 145mm 185mm 260mm 300mm Edison Bulb Lamp Parts COB LED Diode Decorative DIY - AliExpress I chose pink and green as the colors. Other than that all you need is a switch, battery contacts, the CR123A battery, and some wire and heat shrink.
These filaments are available on Amazon as well, however I was not able to find a pink at the time of making this post https://a.co/d/ebBdGNZ
Other than the LED filaments above, here's what I used:
Negative terminal: https://www.mouser.com/ProductDetail/Keystone-Electronics/5204
Positive terminal: https://www.mouser.com/ProductDetail/534-5226
Switch: https://www.mouser.com/ProductDetail/179-SLW-1276864-4A-D
Or, you can remove the battery terminals from common battery holders (such as those for the CR123A)
I printed this sign with a 0.4mm nozzle at 0.24mm layer height. Print orientation is front face down on the print bed.
And you're done!
