M3 Lee 1:100

I had trouble printing the source model at 1:100 (56% scale). The track fenders were too thin and I couldn't get the detail on the bottom of the hull to look decent after pulling off support. So I edited the model a bit in Blender to work around those issues. I thickened the fenders and split the hull into a top and bottom piece with a stud to align them together for glueing. I gave the top turret its own peg, and made both turret pegs separate: the holes they go into are female on both ends so the turrets can be printed without support.
