Percy's gun in the second season of The Legend of Vox Machina. Design based on currently available images. From what I have been able to see, the gun has an iron sight that would not make sense if the four guns rotated, so for now I will assume that they remain static.
It can be printed in resin or filament. It does not require additional parts to be assembled, but I recommend sanding the joint points a lot before trying to assemble it.
