The file 'W78 Thermonuclear Warheads (x3 Payload) Inside MK12A Rentry Vehicle 3D Printer Model' is (stl) file type, size is 695.9KB.
To the best of my knowledge, I designed this following numerous photos, designs, blueprints and a little bit of guessing (when it comes to the classified components within the core). 3 W78 Thermonuclear Warheads inside of a Mk-12A Reentry Vehicle that'd be typically adjoined to a MinuteMan III ICBM.
Typical yield was 350 megaton per warhead, and now have the ability to have up to 7 individual warheads mounted behind the nose cone.
There are multiple versions within the files, some are completely assembled (print in place) and some are completely assemble-able.
Let me know if you find any issues and I'll be glad to fix them!
Update: 9/7/18
•W78Warhead-_cutaway_fixed.stl - updated to have alignment hole in base
•W78pit+_guide.stl - resize alignment hole
•w78mk12_RVx3_payload_completely_assembled_cross_section.stl - resize alignment hole
•W78 pit + guide cross section.stl - corrected upload to have cross section
•Suggest printing at 20% and increasing walls. Model may become fragile when fitting together components.
