Laser from Voltron Lion Force (1980s)

I vaguely recall it clips onto the tail of like the blue Lion? This is as far as I'm going to take this particular piece of nostalgia obscura - the only thing left is to wrap the ridges on the grip all the way around, which is proving irritatingly difficult in FreeCAD and I CBA to learn how to do it properly in Blender or similar; if it's important to you, I give you my full permission to remix it. All files included.
