Making a CNC Hammer Joint Box

OK so whats the big deal on this?  Well the author build this with a drill based CNC (NO LASER).  Which to me is important since most of my CNC projects are bit based.  And most designs/build I find on the net are either 3D printing or laser cutter based.  That and its a cool looking box that can be put together without nails based on the joints.
