Maritime patrol and bomber derived from the B-24 series.
Because it was meant to operate at low altitudes, the dorsal ball turret and turbo-superchargers were removed and a second ventral turret was added. The vertical stab was determined to be more stable than the twin tails of the B-24 and the waist gunners were given powered turrets with dual .50's.
They also served as hurricane hunters and aerial firefighting water bombers.
model in full dimensions in blender 2.80 and exported from blender 2.79b* at 1/100 for the .stl file
scale down to 35% in the slicer.
I've had issues exporting .stl's from 2.80 for Cura; 2.79b and 2.80 export the same mesh to different file sizes, too. So I export the mesh from 2.79b for consistency's sake.
as usual, the d6 is 15mm for reference
