Pack update:
Added a few things, subtracted a few others. As you'll notice, I got rid of the “tape wire” to make it look more industrial instead if makeshift, like the original packs. I also widened the pack as well and put everything on the right side of the pack over, but not far enough so I'll correct that tonight. I also added some details to the pack as well. The details are on the top of the N-Filter, the tube where the gun attaches to the pack, the panel for the control crystals (its in the center of the pack), and the side of the pack as well. I also changed the style of the readouts on the little screen above where the wire to the gun attaches to the pack.
But the biggest addition I've added to this pack is the pump lever. For anyone who watches any of the Stargate shows, the species a.k.a. The Ancients, that created the ZPM although highly advanced also had push buttons and levers on their advanced devices as well. So the idea behind this pump lever, on the side of the pack, is to eject the ZPM from the pack itself. One pump to eject the brace that holds the ZPM in, the second pump pushes the ZPM out of the pack half way so it can be removed.
