Blohm und Voss HA-137 dive bomber prototypes.
3 versions for 2 different engines.
It would have beat the Stuka at trials ( maybe ) but the Stuka was a shoe-in for political reasons.
model in full dimensions in blender 2.79b and scaled to 1/100 for the .stl file
scale down to 35% in the slicer.
as usual, the dice are 15mm for reference
if I can't print it, I don't post it.
