This is a design for a hexacopter with body and motor mounts and arms that can be
3D printed. I stole shamelessly from this project for the motor arms:

and I got some design inspiration from this one for the body
structure, etc.:

All parts were designed from scratch in Solidworks. I've submitted
.STL files, but the solidworks files are available on request.
Thanks to Brendan22 (first link above) for getting me pointed in the
right direction with parts acquisition and directing to the arducopter
website.
I designed it so that the forward looking arms angled this way to make more room up there for a FPV camera or Go-Pro gimbal, etc. All of the motor mounts have the standard 16mm radius mount hole pattern, and are oriented at 60 degree intervals around a circle centered near the center of the body. The GPS/Compass mast is for the 3DR module found here: http://store.3drobotics.com/products/3dr-gps-ublox-with-compass .
