This is a (mostly) static model of the NS Baron G5 from the game Planetside 2. This is the first shotgun added to the game by the Nanite Systems corporation.
It's been split into parts for your convenient printing. All parts except the receiver can be printed on an Ender 3 or similarly sized machine. The receiver is too tall for the Ender 3, and was done on my CR10S Pro V2. You can split it further with a program like meshmixer.
Requires glue for assembly.
The author marked this model as their own original creation.
