mbt-70 tank for micro-armor
The MBT-70 never made it into production, but many ideas went into the later M1 Abrams and the Leopard 2 series.
modeled in blender 2.79b using a model by Prof Null from blendswap as a guide ( some of the turret details aren't modified enough for me to feel that its not his work )
modeled in full dimension, then scaled to 1/100 in the .stl
You'll need to scale to 35% in your slicer.
I printed the hull nose down and the turret gun up, but I guess people will use whatever methods work for them.
