Assembly instructions

Paint the insides of the insert with chrome paint to help them reflect light.  Paint markers work well for this step.

Run the wires from each inside corner of the insert through the hole to the outside and then use some glue to keep them laying in the valleys along the outside till they all collect in one corner.  I found it helpful if all the positives approach that corner from one direction and all the negatives from another.  Then solder on a wire to attach to the battery holder.  It's possible to keep the solder connection inside the ear ring and have just two wires come out to connect to the battery.

Attach a section of jewelry wire to a channel of the ear ring insert that can be used to connect it to the battery.  Put the insert into the outside section of the cube so that the jewelry wire and battery leads exit through the hole in the outside, then install the insert cover.

Run a length of jewelry wire from the bottom front of the battery holder out the top and then loop over and back down half way to create a loop where you can attach an ear ring hook.  The front of the battery holder is thinner and has a channel the whole length for that piece of wire to contact the positive terminal of a CR2032 battery.  The back side of the battery holder is thicker and has two separate channels.  The top one doesn't make contact with the battery at all.  The bottom one does make contact with the negative side of the battery and can be connected and disconnected by inserting or removing a short section of jewelry wire.

Connect the jewelry wire from the cube to the jewelry wire going to the positive terminal of the battery.  I made a joint here so they can swing but a single piece of wire holding the battery and cube in place could probably work too.  Solder the positive lead from the the LEDs to the jewelry wire on front side of the battery holder.  Solder a short section of jewelry wire to the negative lead from the LEDs.  This is the switch and is turned on and off by inserting it into the bottom back side of the battery holder.

Cut and insert one way mirrored acrylic into each face of the cube.

Instead of using UV paint on the inside edges and a UV LED to illuminate it I used a color changing LED in each corner and chrome paint to mirror it.
