Defcon 201 Bell

My 3d printed interpretation of the Defcon 201 logo http://defcon201.org/

A bell with the Defcon logo on one side & DC 201 written on the other. There is a print in place knocker for the bell.

Prints with no supports. I have had some difficulty removing it from my printer bed, it is a tad fragile. Please leave feedback about your experience so I can tweak the model.

update I added an STL without the knocker, should scale down without problems & print easier
