Halo 2 Anniversary SMG

Updated: Jun 27, 2022

A completely remastered model of my ODST SMG to match the remastered masterpiece that is H2A

It's been years since I released one of my most popular models to date, the ODST SMG. Since I have gained lots of experience in modular weapon builds and functional moving parts, I thought it was time to go back and add all the additional features people have been asking for. I reworked the entire model from scratch to match the much higher fidelity H2A SMG model as opposed to the previous Halo 3: ODST model.


Major Features

Detailed Modular Design

This model is comprised of over 40 unique pieces, including interchangeable foresights and barrels. All structural components of the SMG slide/screw together to make for an easily interchangeable and customizable build.

There is no need to worry about sanding away any ugly seams as the model is sliced in such a way to match the natural edges of the model itself. This makes sanding and painting the model much easier and does away with any worry of the finished product snapping across some hidden glue line.

The full SMG is around 35 inches (89 cm) in length. This size was taken from the official cosplay guide for The Rookie and his SMG. Additionally the length listed in the Halo Wiki makes for a very small SMG that feels more like a toy. I personally printed the SMG at 70% scale as I am shorter but still wanted a large, fuller feeling prop.

Adjustable Foregrip

The foregrip utilizes a simple, friction based design, matched with built-in geometry to allow the foregrip to rest at its natural deployed angle, as well as a compact, in-line position.

Adjustable Stock

The stock utilizes a simple, one-spring lever button mixed with a saw-toothed rail system to make for a stock that can be set to a number of secure positions all with the simple press of a button.

Checkout the assembly video to get a more intuitive feel for how the design works.

Removable Magnetic Magazine w/ TV remote style magnet fastener

Everyone loves a magnetic magazine. What they don't love are those magnets pulling away from their glue and flying all over the place.

This magazine allows you to place your magnets inside of a clip that fits inside of the main magazine body the same way you place a battery cover on a TV remote. This allows the magnets to sit freely within the case with no chance of actually escaping. There is a mirrored clip that sits inside the body of the SMG that allows the magnets to secure the magazine to the body.

There are multiple clip options to account for different sized magnets.

One additional note, is that because the clip utilizes some internal bending mechanics, it needs to be printed in a side-touching-the-build-plate orientation. This ensures that the layers run the length of the bending portion and makes the piece bend rather than snap.

Interchangeable Barrels

This model contains two options for the barrel, both of which securely screw into the main body.

The first barrel is the classic H2A knurled barrel and the second barrel is the ODST Suppressed version, featuring flashlight attachment. The flashlight is a separate component to allow for small personal flashlights to be put into the attachment. If you require any help printing modifiers for your flashlight, feel free to message me.

Additionally the flashlight attachments as well as the SMG body features small openings for Wires to allow for that wired connection from body to flashlight that is featured in Halo 3: ODSTs version of the model.

Interchangeable Sights

This model comes with two sight options, the classic H2A iron sights and the ODST red dot sight.

The iron sights, fit into the main body of the SMG while the red dot sights fit on top of the iron sights get into its secure position.



This build was a fun, easy to print project that came together so well. The satisfaction of the magnet clips *clicking* into place and the stock sliding easily over its rail was so rewarding. I didn't want to hold onto the model while I painted it so I still have that ahead of me and I will update my pictures once I have my finished painted prop.


What Next?

If you are looking to create you own models like this one feel free to checkout all of my tutorials on 3D modeling and prop making techniques.

If you are looking to purchase the model so that you can print your own you can find it in the store.

Lastly, make sure to check back in every once in a while to see what I've been working on

Thank you for your time
