About this 3D model

Perhaps you're putting together a stage version of Goodfellas or are making a cool mobster halloween costume - if so, these are for you: a makerbot-printable version of that hoodlum icon, brass knuckles. Disclaimer, sort-of: These are specifically not to be used as a weapon of any kind! Searching the internet for some pictures to guide my design, I discovered that actual brass knuckles are illegal in many places. So far as I know plastic stage props are not, but be careful.
