Russian cold war bomber developed from the TU-73, which was a 3 engined plane that lost out to the IL-28 Beagle.
model in full dimensions in blender 2.82 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
