I have two cylindrical bodies to print on a Taz 5 FlexyDually. I've attached the STL files if anyone is interested in trying it for themselves.
In Fusion360 it looks like this (the blue highlight is the "wheel-support" model).
I realise I could just have Simplify3D figure out the supports, but this is just a test of my ability to use a model file for the support (HIPS filament).
