Green Lantern LED Lights Remix
This is about 3.5" tall and uses two 5MM Green LED's. They are powered by a rechargeable 3.7 Volt LI-PO battery from an Estes Proto-x / Hubsan Q4 nano quadcopter. You just need to be careful that you don't let the battery drain completely as it is possible the battery will be damaged and unable to recharge. It uses the quadcopter USB charger to charge the battery.
You will just need to cut off the end of the charger and LI-PO battery and solder new connectors. I used Male & Female JST SM Connectors 2 Pin.
There is an on-off switch for the lights and also a charging port on the bottom to charge the LI-PO battery.
All the pieces are attached with super glue after printing.
A piece of 1.75mm filament (green of course) was used for the handle
