This is a reasonable facsimile of the Peacekeeper (LGM118) ICBM. You may find that, depending on the scale you desire, you may have to use the split (cut 1 & 2) versions of stage I rather than the whole model. The Nosecone and raceway end caps are meant to be printed in silver.
UPDATE 4 Nov 15: After a lot of work interpolating measurements from technical data, I've incorporated the pads onto the appropriate stages and the RS. These models are ideally meant to be painted, but as with anything Thingiverse, do what you wish. If anyone is interested in the tedious process of printing and gluing the pads in individual colors, let me know and I'll post those files as well.
