One thing you'll learn if you take up 3-D printing parts for production machines is that you design parts differently than you would were you making the parts using a subtractive (typical machining) method. In the case of the clam shells, a floor is necessary where a smaller diameter pocket is atop a larger diameter pocket (inverted counter bore as in one of the clam shells). Indeed, anything that is free floating requires seriously thought since extruding into empty space yields a predictably bad result. The other thing is that parts don't have to be rectangular to facilitate machining. You can design the part however you like and I typically avoid sharp corners not just for aesthetics, but also to minimize filament consumption. This is why I'm so interested in incorporating FEA into 3-D printed part design - 3-D printers are just capable of so much more. Designing for 3-D printing really forces one to think differently, another likable aspect, in my opinion.
