Broken Tank

As promised, I'm going to load photos of my first tank. This is a 6mm doodle based on an American M1A2 with a railgun, making this model the size of a quarter. This model will not print in any way, shape or form. There are probably 100 problems with it, not including the poor design practice. How many problems can you see? How would you correct them?

My next post will feature fixes and a cleaner, updated version of the tank. Stay tuned!
