This is by no means an easy task, and requires decent CAD modelling skills. As an answer to this question would need to be basically an entire CAD tutorial, I've voted to close this as "too broad". You might be able to limit the scope of this question by considering just one 3d modelling package (as right now an answer could address one of a 100 modelling tools), but even then it is too broad in my opinion.

You're going to use a lot of unprintable words while dealing with this unprintable shape :-).   If you have a model w/ enough sub-elements, then just delete all the elements not visible from the outside.  At that point you *might* be able to slice and specify infill; most likely you'll need a bunch of support posts specified if you want a detailed undercarriage.

"unprintable words"  Nice.  :-)

James, what is your starting file format.  Is it an STL or other?  Maybe that will help narrow down your question and you can get a specific answer that will help.  Also, if the file is online, maybe you could add a link?

I would recommend "The Maker's Muse" youtube video channel.

In particular this video [Fixing impossible STL's with Meshmixer 3.1.118 BETA](https://www.youtube.com/watch?v=8ECNP3WN_-Q "Fixing impossible STL's with Meshmixer 3.1.118 BETA") might solve your problem.
