Body Shell for KITT

I did a lot of modeling work to convert JulHa's KITT model into a shell that I could use for an arduino robot. JulHa's model is good, but very much not printable as is.

I left out the arduino frame bits I made/used because they only barely worked for the job, and I'm not willing to do the modeling work for a version that is ready for you.

Likewise, I did not model wheels because I did not need wheels.
