Hi,  
I made a 3D design and it has a lip for a top to slide over. When I print it the lip doesn’t print. I think it’s saving as a second body. I need them to print together. Please advise. Thanks

Tom, go to Tools, select all or both bodies, then use Union to bring them together. This should resolve your issue. Tom McD
