Here is my object:

I’m trying to print 2mm thick shell, hollow (support everywhere), and I want to print the ring around the bottom of the object as part of it. The trouble is when I check ‘solid bottom fill’ in the print settings it prints anentire filled in circle, and if I uncheck ‘solid bottom fill’ it doesn’t print the ring at all. Any suggestions? Thanks!

I would run the model through a checker such as netfabb or makeprintable.com to make sure it is manifold and no other issues are present.
