Led Love Written

That project is made by six parts and could be assembly without glue.

1. To assemble it I welded to the LED strips of small cables that I put through the holes.
2. Then I inserted the LEDs in the letters and then inserted the letters in the support.
3. I soldered all the positives and negatives on PCBs connected to the circuit breaker.
4. I also installed a 600 Ohm resistor to lower the voltage from 18V to 12V (to generate a voltage of 18V I used two 9V batteries in series).
5. Finally I placed the back cover to close the whole thing.

I used the “Pink PLA Matte ” of Bambu Lab for the external case, “Lavander Purple PLA” of PolyTerra for letter L and for the heart and “Fucsia PLA” of SUNLU for letter V and E.
