Hey, KingRahl.
I found a download for your Magna Defender chest and DinoThunder White chest armor as I plan to make 3D models of both characters.
I was able to convert the Magna Defender chest armor but I can't do that with the DinoThunder White Chest armor.
In fact, when I try and open the file with Pepakura Designer, the file closes the program and opens up Pepakura Viewer instead. Weird, huh?
If you can, send me a converted OBJ file of the DinoThunder White chest armor and I will make sure you receive full credits when I finish that dude's model.
