This is a "Pack-A-Punch" machine from the video game "Call of Duty" 

My buddies had a real life replica for one of our Dungeons and Dragons game and I found it super well made. 

The model was made out of wood and plastic, painted over with paint. 

This real life model is not watertight, but I wanted to recreate it and make a water tight model. 

I created a remodel of the Pack-A-Punch in Blender

Used simple lighting to illuminate the object

Placed a rectangle in the triple barrel section to make it watertight

Went through multiple versions to 3D print

This is the 3D printout of the image

I closed off the holes to make it watertight, still trying to leave small holes to represent the large triple barrel grinder hole and both the small and large signs.
