I wanted to create a dog poop bag dispenser that was not boring and plain, but something that would make people laugh. So I came up with the idea of making it look like a grenade. It's a fun way to say that dog poop is explosive and dangerous, and that you need to dispose of it properly.

I tested the dispenser with different sizes of bags, and it worked well with the ones that are common in my area. I don't know if it would fit other types of bags, but I hope so.

I had only black filament at the moment. A dark olive green, matte colors or some metallic filaments would probably look the best.

Some dimensions to check if your bags should fit:
Inner diameter: ~39,7mm (1.56 inches)
Inner height: ~68,7mm (2.7 inches)
Inner vertical pin for the core: ~6.5mm (0.256 inches)
