I'm just going to quickly go through these steps just as a quick reference guide for those interested:
Building a pair of bracers for my wrists and another pair for my ankles; the idea is they have to LOOK heavy and feel solid while being easy to put on and take off.
I began by cutting blue foam into the desired shapes (the hexagon ones are the bracers, the crescent pieces are for another part of the cosplay).
After drilling and sanding out the holes in the foam and getting the ideal dimensions, I cut them in half and sanded down the fresh edges some more. I used epoxy to glue the pieces of plywood onto each of the edges.
Using the laser cutter, I made these "lids" out of 1/8" masonite and used double-sided tape to hold all the halves back together.
