Let There Be Light

Tired of not being able to see the details on your 3D printer. Then learn how to hook up a LED light to your printer with only $3.

Step 1: Materials & Tools

Wire Cutters
Wire strippers (optional)
Solder Gun (optional)
Heat Gun (optional)
Pliers (Optional)

Car Angel Eyes Round Ring 1210 18 White LED Light Lamp Bulb Headlight 60mm Model 1
2x 18cm long wires ~1mm thickness
3D printer
Heat shrink (optional)
Solder (optional)

Step 2: Cutting Wires

1) Cut the ~18mm wires and twist them together so it is easier to deal with stray wires.
2) Then cut the connection off of the LED light.
3) Twist the LED wires to the extension wires. (optional to solder them together)
4) Solder the end of the extension wire so you can push it in the printer connectors. (optional)
5) Use tape or shrink wrap to cover the exposed wires from touching anything.
6) Push the extension of the LED wires into the 12v pins where the power directly connects into the printer !!!Make sure they are inserted correctly (positive to positive, negative to negative)

Step 3: Connect to Printer

1) Turn the ring to slide it between the fan and the extruder.
2) Use a zip tie to hold the ring in place (don't make it too tight)
3) Connect the wires for the extruder heater and temperature sensor.
4) turn on the power and Boom, you have light

    Hey that is actually a really neat way of lighting up the build area. My replicator 2 has a led strip and the extruder blocks most of the light. Im definitely gonna try this out. Im just wondering where you got your led ring and is there an RGB version available.

    I think they have other colors like blue and red. I think the white LED are awesome since they are really bight and the illuminate your whole workstation. If you want to dim it down. Just add a variable resistor.

    Maybe this will work if you want to pimp out your 3D printer:
