Recently bought a led base for LEGO character, but I don't have idea where to buy the character, so I print it with transparent filament.
Step 1: Print and Make the LED Base
The led base can make with 5x 5mm RGB Rainbow LED, 5x it better than 4x or below. ~~5v0.5a power input.
3D stl file
The minecraft creeper has 10% fill in, it should be better with 0 fill in, and you can use acetone to make smooth finish.
Thats all I want to show you, 3D printing + LED
