How to create this kind of connection and the fillets for it?

Hello,

I am sitting here for moe than 2 hours already on that object and I just can't find a way to create this bottom body of the shape. Especially the connection between the extruded circle and the extruded "hexagon" with chamfered edges.

When I union those 2 parts with my "connector" part it is just not connecting properly and I am not even speaking about filleting. Is that kind of object that complex?

Is there maybe a different way to create that kind of shape than with my method? I am pretty new to MoI3D still and I have to do that shape for a client, but I am just absolutely stuck.

Thank you, Nikita
