Careful. Don't Answer Your iPhone Gun Around Trigger Happy Cops

This little bad boy is lots of fun, but I'm not sure I'd hold it up to my ear in public... especially wearing creator Junior Tan's menacing facial expression.

The best part about the iPhone revolver? There's a HowTo.

Junior Tan created his Ruger LCR Revolver iPhone case using 3D printing technology on MakerBot. It's easy. Just three simple steps: download the digital 3D model at Thingiverse, print and glue:

"The trigger guard (for authenticity purposes) is a little thin. At some points its only 2 extruded filaments wide. I filled up mine with some krazy glue. The iPhone cradle is a little long, as I had to create audio channels and a space to attach the dock connector.

If you are a leftie, just flip the cradle around before gluing everything together."
