I wanted a power pack to outfit a devastator squad with multi meltas so I made this, might work for lascannons as well I haven't looked yet to see if they are any different. This utilizes the basic frame of the vanilla pack so they will mount up nicely to the modular mk4 marine torsos as well as BREXIT's space marine torso, probably others as well. Now rain fire down on the Emperor's enemies!

NOTE: I haven't included the tubing yet because I'm going to need to spend time shaping/scaling the tubes to fit around the marine and to the gun correctly. It'll probably be something i print in segments so you can put it together yourself. In the meantime all I have done is the pack which may work fine if you'd rather use some actual wires or something.
