Chassis for first class coach or guards coach

A chassis for Tebee's first class four wheeled coach http://www.thingiverse.com/thing:158282 which I have created for my railway... The height is to suit my loco's and it uses Graham Farish wheels, 379-410 which simply pop into the axle boxes. There is a space under the coach for lead ballast and the bufferbeams are the right height for greenwich couplings to sit under. I print using support. Have fun!
