Hi beanworks - so that's really quite a really complicated job that the filleter would have to do there, particularly on the bottom part where there is a complex corner area here:




I'm not sure that the fillet engine is going to be able to figure out how to put in a corner patch in that area that has pieces that are opposite facing all connecting together in that spot.

Also right near the same area, the edge here:



The 2 surfaces that meet there are pretty small and come to a narrow point - there is not much room available there to place fillet, even one of a pretty small size is going to try to eat away an awful lot of area out of that little narrow wedge there - so that kind of shape and complexity is probably going to prevent the bottom assembly from being filleted in MoI at least, possibly another CAD system that has a more advanced fillet engine might be able to deal with it better.

The top part I'd say has a better chance, I'll take a closer look at what you might need to do to get the top part filleted.
