This dual gatling turret can be used for all sorts of sci-fi tabletop games. I've kept it the size that I use for my own . But if you scale it up a bit the detail really pops.

I've included two different styles of this turret. One has all the pieces separated and lets you rotate the turret 360 degrees.

The second style only has 2 pieces to keep it simple, though you cannot rotate the top.
