Diamond shaped LED desk lamp. Approx. size 3 1/2" x 2 3/4" x 2 3/4" Uses any old 5 volt cell phone charger to produce a quality visual effect. Some electronics required.Print all parts with raft, no supports required. I used 1 shell with 50% fill. Takes about 2 hours to complete this project. Use a 5Volt, 500mA cell phone charger, with a 100ohm 1/4 Watt resistor in series and an ultra-bright LED. Slide the diffuser over led, glue down the wires and then glue the shade to the base. Much time was spent on the diffuser to get even lighting I'm really happy with the result. Enjoy!
