Dog Poop Bag Holder – MK2 grenade

Plant. Pull. Clean. Sector clear.

Every dog walk is a round.
Every poop is a danger zone.
This is your utility.

Inspired by the iconic MK2 grenade, this poop bag holder turns an unavoidable task into a tactical move. It looks dangerous, but its only mission is to keep sidewalks clean and walks stress-free.

Features

• MK2 grenade–inspired design
• Fits standard poop bag rolls
• No glue required – fully screw-assembled
• Easy side access to bags
• Easy to open, refill, and clean

Loadout

The leash keyring loop is also 3D printed (because I didn’t have a spare one 😄).
Can be replaced with a standard metal keyring.

All parts are printed, tested, and assembled without gluing.

Tactics

When your dog announces “fire in the hole”, you’d better be ready.
Grenade deployed — sector clear.

UPDATE:

At the request of user @skiboprints, I created a reinforced model of the screw that holds the key ring. I also added a new profile that allows printing just the screw, as well as a new profile for printing the entire assembly in a reinforced version.

🛠️Before You Start Printing

Before printing, give the bed a quick clean 🧽 — good adhesion = better first layer and accurate geometry.

Use dry filament (wet filament loves to pop, string, and ruin dimensions).

When using my MakerWorld profiles, make sure the selected material matches what you’re actually printing. Different materials shrink and behave differently — the wrong profile can mean wrong dimensions.

Also, my STL files are designed and dimensioned for PLA. If you print them in PETG, you may need to slightly rescale the model to compensate for different shrinkage.

Clean bed. Dry filament. Correct material. Done 😄
