Hi Gary, I've attached another version here with some additional partial fillets added - these were done by separating the model into individual surfaces and selecting 2 surfaces at a time to do a surface/surface fillet.

You can kind of see here how there is some difficulty with multiple fillet pieces running into one another and needing to kind of disappear into a single point at the top parts - MoI's filleting engine is not good enough to handle those areas automatically. That means you may need to trim away some portions of the model and construct some surfaces in there manually to patch things together.
