After tossing a few ideas around and making a few sketches, I worked a design up in Cinema 4D.

Many, many hours later... it finally finished. After getting rid of the scaffolding/brim and cleaning it up a bit with a dremel tool, it doesn't look too bad.



Both the design, and the print are far from perfect - but I consider it a successful proof of concept. I've already made a number of tweaks to the design, and am planning a higher quality print in the future.
