Fig 20. Finished carbon fiber mold (upper housing on left, lower housing on right)

Fig 19. Vacuum bagging - breather and teflon fiber glass put on top of the mold to absorb excess resin

Fig 18. Carbon fiber layup (upper housing) - 3 layers of carbon fiber cloth along with epoxy (105 Resin and 206 Slow hardener)

Fig 17. Gel coat mold release - Although the outer surface of the 3D mold had about 10 layers of mold release wax, it was still very hard to take the fiberglass mold out without damaging the 3D mold.
