About this 3D model

This is a bracket to hold three 5mm LEDs to light up the build platform around the extruder tip for a Printrbot Simple 2014 (with the aluminum extruder and the fan with hood.. I used 3 5mm white LEDs wired in parallel through a 5.6 ohm resistor to 5 volts on the EXP1 OR EXP2 connector on the printer board. If you wanted to connect to 12v, you would need a 15 ohm resistor to feed the three LEDs in parallel. Alternatively You could wire the LEDs in series through a 12 ohm resistor to 12v. Enjoy...
