Here's some of the build process and .stl file for my 1:1 prop scale Whisper. Whisper is the bow that the Warlock Lylyth from Privateer Press uses in the tabletop wargame. I enjoyed the look for the bow so much, I constructed the model so others could print it out full scale and hopefully enjoy it as much as I do. The only reference shots I had were the two shown in the files list above, everything else I had to scale off of her height and lay flat before adding the very organic cross-sectional details.
I've got more prop scale replicas, model bits for 28mm scale wargames and a Pelican from HALO: Risk which is one of my bestsellers over on my Shapeways page. http://www.shapeways.com/shops/replicaforge
