Pingu themed Paintball Barrel (Cocker Thread)

Usable as is, no freak insert required. The barrel will be loud AF, as is usually the case with super short barrels.
To improve performance or if you're breaking paint, wrap a piece of sandpaper around a stick and smooth out the inside of the barrel as good as possible.

Print flat on the front face for best stability while printing.

Yelling "Noot Noot" while bunkering someone is now mandatory.

Noot_Noot_Barrel is about 18cm in length
Noot_Noot_Barrel_245 is 24.5cm in length

Added f3d file for you to customize, be wary of the internal diameter when editing the sketch dimensions.
