Things you need:

  • Two 5mm 3V Red LEDs
  • One CR2032 3V Battery
  • Two M3*8 Screws
  • Two M3 Nuts

Assembly:

  1. Bend each of the LEDs' pins so the ground pin is above the positive pin (Look at the images if you're unsure how to bend them)
  2. Superglue the M3 nuts into the holes on the back of the top part (wolf head)
  3. Put the battery between the bent pins of each LED so that the ground and positive pins of the LEDs touch the correct side of the battery. If you hold the LEDs' pins to the battery they should light up.
  4. Put the LEDs with the battery into the hole on the bottom part (check the pictures if you're unsure where they should go, the grooves on the sides of the battery hole are for the pins on the LEDs to reach under the battery)
  5. After the superglue on the nuts has dried put 2 M3 screws through the holes on the bottom part and screw them into the nuts on the top part.

This should be tight enough that the LEDs' pins make contact with either side of the battery and light up. If you're having trouble lining up the bottom part because of the position of the LEDs, I used a bit of force and the LED pins bent into the correct shape to allow them to fit into the top part.

Note: Infill at 100% is ideal so light doesn't leak through the plastic
