Meshmixer is your friend here. You could use either the "Extrude" command with a negative offset in the normal direction to create a second smaller body or the "Hollow" command and set your preferred wall thickness and then make a cylinder to cut out using Boolean subtraction to remove the second wall that's in the way.
There's a few other ways to fiddle around with the program using plane cuts but extrude and hollow are definitely the easiest.
E-mail if it is less than 10MB (moesizzlac (at) yahoo (dot) com). Dropbox with a link if it is greater than 10MB would be preferred.
Meshmixer is a great tool too. I don't have a whole lot of experience with it though but I have seen great things done with it.
Me, since I have some blender experience, I would probably start by stretching and skewing the inside portion of the model. If that fails, I would delete it and add a solidify modification to only the outside model to create a uniform wall thickness that works for printing.
I modded the non fixed one and gave it a wall thickness that should be alright for printing. If you want the wall to be thicker, I can also do that. Sent it to you as a .zip because yahoo mail was giving me trouble sending a .stl.
