Halo Infinite M247 Machine Gun Turret Tutorial/Build Log (505Forge and 405th SouthWest Collab)

tahu505 Took on a commission from me to make the 3D model for the M247 Machine Turret from "Halo Infinite". I think he did a spectacular job. After posting the model to his Etsy page he mentioned that there have been some people requesting a tutorial to assemble the thing.

So here we are, I will attempt to layout a thorough tutorial for anyone that would also like to build this absolute beast of a prop and have it on display. Be prepared to read a bit, I will also have plenty of photos to make it easy to understand. I'm writing this whole thing day by day as I am building it. It'll likely feel more like a "Build-along-adventure" instead of a legit tutorial.


**Disclaimer : There will likely be plenty of things I don't mention in the best detail, under the assumption that you may elect to do this in a different way. The main thing I want to get across is what parts of the models are where and how they connect. As an example, I'll be using adhesives that maybe you don't want to use or have a different preference, I'm not saying this is the only way to do it. Get creative.

The first thing I would recommend is the use of a 3D modeling program that gives you the full picture before you print anything. This will at least require you install/open something like 3D Builder(A free Microsoft 3D modeling program that I use, it's really simple). This is a great way to understand how the whole thing assembles before you might make mistakes with physical parts. It's also the program I am using side-by-side with the real thing. When you have the program open and you load all of the files from tahu505, the 3D models will position themselves into the fully assembled prop. It may take some adjustment to get things in the right spot depending on how you load each file, but that'll help learn how it goes together :D

Things you might need:
  • Adhesives and fasteners. I'll be using E600, Super Glue(Cyano Acrylate), and some miscellaneous screws/bolts. Hot glue could work, but with how big this thing is you really should find much stronger alternatives.
  • 3D Printing capability. I don't own a 3D printer anymore, but I have many friends that contributed their printers to get this done. Including BlazingForge / Insta, thatdubejobo, GalacticWombat / Insta . SalLyrisse / Insta provided emotional support and finishing
  • Paint. I'm using spraypaint and acrylic
  • Tape of different types, for mock-up, glue support, and painting
  • 3D Modeling program like mentioned above
  • PVC Pipes, screws, bolts, wooden dowels, metal studs. tahu505 's files provided a part list for essential items, I will likely use some extra stuff.

Approach the MG slowly, it doesn't like to be startled
I'm dividing this whole project into 4 main sections. This is how I sorted all of the parts before sending it out to print with each person that helped.
The Frame: Parts that really keep the whole thing together or need to be really strong.
The Barrel and Shield: Don't need to be the strongest, helps to make this light. A PVC pipe will reinforce as the core
Details: Good to make these with high detail and quality. More intricate than the other parts.
Tripod Legs: Make it really dense to give the whole assembly a great foundation, there will be studs to fit the legs to reduce print material/ add strength

*Using a mannequin model with the same height as you can give a great perspective for how huge this thing is.

The Frame:
We're gonna start with the most complex section first and get it out of the way. As mentioned above these will be parts that really contribute to how strong the overall print is, it really provides all of the structure and the ways that you can carry it. Don't skimp on the density for these parts, it may add to weight but you'll appreciate it not breaking too easily.

The rear of the frame is your "triggers" and operators position. There are 4 handles on this thing, two you would grab to make bad guys go away, and two that allow you to feel like Jorge for a bit(there is an Etilka version provided by 505Forge if you want that variation)

These go together easily. Make sure you pay attention to the pointy engravings that stick into the other parts of the frame, they line up with it.


Main Frame. Not sure what to really call this area. It holds the back of the Barrel, as well as the handles, and the hip. It's essential. Luckily the parts can only really fit one way, and you'll be able to click them together and try it out before final adhesives.

Love the work... the process... the writeup.. the result. Just great.
FYI: The choice of black text is hard for people with web browsers (or just this site) in `Dark Mode`

Tip for those that have their browser in Dark Mode: You can select the text in those areas to highlight and read it.
