Assembly Materials (for one earring)

NOTE: the LED burns through the batteries because there is no resistance. I suggest adding a resistor somehow. These instructions are how I originally assembled my earring set.

• TARDIS and Plug STL files

• LED - 3volt

• 3x 1.5volt LR41 Button Batteries

• Masking tape (non-electrically conductive tape)

• Earring hoop

• Jewelry jump hoop

Assembly Tools

• 1/16th drill

• Needle-nose pliers

• Wire cutters

Earring Assembly Directions

1. Print TARDIS (use the pair files if want a pair)

2. Drill using the 1/16th drill to put a hole at the base of the nub on the top of the TARDIS (pictured).  This is probably best done via hand and not a powered drill.

3. Insert a jump ring into the nub hole and the earring hoop.  Use the pliers to close the loop.

Light-up Earring Assembly Directions

1. Print the plug (use the pair files if want a pair) - this can be performed with Step 1 of the Earring Assembly.

2. Tape the button cells into a column leaving the top and bottom clear of tape.  Make sure that the batteries all have the same orientation (ie positive to negative connections).

3. Bend the LED wires into the configuration pictured.  The longer end of the LED wire is the positive and needs to make contact with the top of the battery column (the smooth top of the battery).  You will likely need to cut down this wire to length.  I also recommend taping the LED lead to the battery column.  Leave the bottom wire such that it is NOT actively in contact with the battery column but that when pressed up from below, forces the wire to connect with the battery column and completes the electrical loop.

4. Insert the taped LED/battery sub-assembly into the TARDIS with the LED at the top.

5. Snap on plug piece to turn assembly on (this forces the bottom wire to make contact with the bottom of the battery column, completing the electrical loop).  Likely will require pressure to snap the plug into place.
