I have a couple cool heat sinks for ya! I'll bring them tomorrow...
I'd cut a piece that matches the bottom of the grip and "cap" the bottom of the grip, maybe adding an accent piece, or a spiky pommel (you can never have too any ways to make a weapon useful!!)
Je me demandais si t'allais utiliser ça comme base pour ton blaster!
Maybe you could do up the barrel with a cooling sleeve to it? Maybe with T-tracks to give it some textural definition? It would just be a 2" pipe with a 1" pipe slipped into it.
A demain!!!
