Sand the outside of the batter compartment flat... glue will stick better and the battery compartments will be much stronger.
Did you know that when you add super glue to the plastic dust it creates a super strong bond?
Scrape the battery compartment ring flat on the side that meets with the bracelet.
Test-fit your parts... snug as a bug on punk rock rug!
Super glue is great and dries in no time. When you press the two part together, align the notch in the ring with the wire hole on the bracelet.
Press and hold for 20 or so seconds... and then repeat these steps for the other side.
We're ready to install the spikes, LEDs, and wire it all up.
