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.

Notes:

The tracks have not been changed or rescaled, so they still need to be scaled down to 56% to be 1:100 scale. The other parts (fixed_*) are already rescaled to 1:100. The upper hull should be printed with support, and the lower hull should be flipped over and does not need support. The big turret should be printed with support (for the barrel), but the little MG turret probably does not need support.

You may need to play with horizontal expansion (or a file) for the alignment stud and turret pegs to fit into their sockets.

Post-Printing

Put the alignment stud in the hole and make sure both upper and lower hull pieces will fit together seamlessly. Then glue the hull pieces together. Glue the turret pegs into either the bottom or top sockets (but not both if you want the turrets to spin). Then glue the tracks on (this is the trickiest bit: some more work should probably done to make aligning the tracks to the hull less error-prone).
