DIY Christmas lights for a small table-top tree

thingiverse

Well, it's probably not worth it to make these lights yourself, since they're really cheap nowadays. But I had some free time and a bunch of cycling RGB LEDs (similar to this) with no idea what to do with them, other than this, so why not. Print Settings Rafts: No Supports: No Resolution: 0.1mm Notes: The bulb parts should be printed in single outline corkscrew mode aka "vase mode". Post-Printing Assembly I soldered a 470 Ohm current-limiting resistor to each LED. Then soldered them in parallel using 2-conductor 22AWG wire. The wire should be threaded through the holes in the socket parts beforehand (see pictures). For the power source I used a 5 Volts 2 Amps wall adapter.
