B-24 Liberator with nose turret. Either a 'H' or a 'J' because I just made up a turret instead of worrying about getting it right. At small sizes, who'd notice the difference anyways?
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
