Light Tank separate turret

I wanted to print the Galleon tank in 15mm and be able to rotate the main turret, so I played around a little bit with the original in 3D Builder - separated the turret from the hull, modified geometry of the bottom of tank's hull a little bit (to make it flat instead of the strange shape it was).
Scaled for 15mm (1:100) scale. To print it in original size, rescale to 40% (but why bother, just use the original files from Drewbs4)
