Another physical prop, NOT a real weapon.
Inspired by the Star Wars imperial E-11 blaster, I built this one from scratch as some evolution of their blaster. I call mine E-11 b-2S. It features double barrel, appropriate scope, laser scope a container for actual fuel to turn into particle beams, a "power pack" NOT looking like a bullet magazine and a "liquid cooling radiator" around the barrels to cool internal components, rather than the air cooling ribs of its predecessor.
This one is made mainly from PVC pies, scrap plastics, brass pipes, aluminium rods and lots of bolts and nuts. The scope and grip salvaged from some discarded toy (I'll build the next grip myself, that'll be easier than re-using).
One tiny part was constructed in Fusion 360 and 3d printed, the front end cap of the fuel container. All the rest was easier to cut, shape and file from plastic scraps.
It does look steampunk, due to the brass cage, but I noticed there's quite a lot of steampunk in the Star Wars universe.
