Lava,
Here is the link to Rafalfett's Shapeways page. There are several file you will need to get. Note he has 1/12 scale and full scale.

You will need to create a free account before you can download the .STL files. The you will need to split the files into parts small enough to fit the printer you have.
This is a big job!
Mine took 7 1/2 weeks from me downloading the files to assembled, painted and a wearable jet pack.
