These all use 4mm magnets, a lot of them, to allow you to connect a detachable neck ring to the Phase 1 Helmet from Killonious.

I used super glue to attach the magnets to the pieces, and after they were inserted, I used super glue to attach the connector pieces to the helmet. The method I found easiest was to first insert all the magnets. And once those are dry, stack all the connecting top and bottom pieces, and put a glob of hot glue on each face that will mate with the helmet and neck ring. Hold the neck ring up to the helmet where it will be, and shove the pieces with the hot glue into the crevice made, and let the glue cure.
