MG3 CAD MODEL
To download the CAD model, you’ll need 7-Zip (download link) — a free, open-source file archiver that compresses and extracts files.
You’ll notice there are two download links. This is because the file is quite large. You’ll need to download both files.
When unzipping, right-click on MG3 on Flat Stand.7z.001, select 7-Zip > Extract Here.
You might not immediately see the folder appear, but if you scroll down in your Downloads folder, you should see a new folder named MG3 on Flat Stand.
If you do, then everything was successfully extracted.
