All the files should be available on shapeways, bar the upper spine, which shapeways had problems with. That is NOT on Dave's shapeways shop. However, I have it saved. Barring any objections, I could forward the file to you. Materialize online were able to print that part for me, so it can be done. It seems shapeways are far to cautious about print some things. I could never understand why they would be able to print the lower spine, but not the top. Apart from a few differences, (pipes etc.) they are pretty much the same thing... As I said,
barring any objections....
