I could easily 3D print 5:1 ogive nosecones (including the integral A.S.P. antenna or at least one with a flat truncated or open tip) in any BT size up to BT-80. The estimated cost in material for ABS plastic (at $15/Kg) is the diameter times the height (both in inches) times $0.30 . Mass production of more than one nosecone at a time will save on time and hence production cost. I have been printing 9 to 25 BT-20 sized ABS nosecones in a single batch.
