You should check out this korean paper master’s website at http://poppaper.net/
It shows some pretty intricate and incredible cut outs of units from the starcraft 2 universe. Although it is korean the models speak for themselves! He has also made a Banshee with detailed 3d models on his website. Unfortunately I don’t read Korean so perhaps he may also outline how to download and make these models.
Here are some of them:
A paper tank that is in siege mode looking rather good! The last time we had a lego siege tank with moveable parts. I don’t think this one moves but its ready to shell some zergs.
And a battlecruiser, another popular unit choice for fans making cool stuff!
And extending beyond mechanical units, there’s even a more circular marauder.
