So I stumbled upon WorldofPaperTanks.com and there you can currently find eight free and high-quality 1/50 paper models of WoT tanks.
I chose to start with the MS-1. I printed it out half as big as it actually is to get it to 1/72 scale.
However, I had to replace the gun part with a piece of wood because the paper gun was simply too small to handle.
Despite him being made from paper, he's quite sturdy. I also reinforced the model with small hard foam plates and made the turret moveable by drilling holes into the paper/hard foam and glueing a shortened wooden toothpick into the hull.
