HO Scale Billboard Frame-Pole Mounted 2

This is an HO scale billboard frame, 24'x12', It is designed so you print your insert on a color printer, cut it out and insert it into the frame. This is a pole mounted billboard. It has supports for a walkway, but the walkway itself is not modeled. My thoughts were to use some etched brass boxcar roofwalks. I also have a version with a walkway modeled.

The pictures are of a wooden version I did. I have not test printed this model yet, but the square frame is the same as in the wooden version, and I think the other parts are OK, but you can't be sure until Shapeways gets ready to print one. If you look at the picture of the shapeways logo, you can see where it sticks out the bottom slightly, showing how the paper is fed up through the frame.
