Billboard

Navigation: Details

Such a large billboard needs a good groundwork. The ground cover is removed, a baseplate made of styrene. The first fine hole is already drilled.

The pole of the billboard is attached to the base with large screws (prototype). This part of the model is made as a 3D-print. I choosed resin with the highest resolution as material. The inner diameter fits exactly the pole width, the outer diameter fits exactly in the base plate of above.
This construction was made by myself with OpenSCAD (https://www.openscad.org), the printing was done by Shapeways. There is a big improvement in quality since I ordered something a few years ago. If I had knew this I would have made some details a little bit finer.
I reflected often about how to mount the billboard on top of the pole - since I was afraid simply glueing it wouldn't be enough. My solution is a threaded rod from top to bottom inside the pole to clamp the billboard to the pole - works fine!
I needed something to look like a real world mount of the billboard to the pole. I ended up with this - a cover to place on top of the pole after having mount the billboard with the help of the threaded rod.
I soldered thin brass wires to these photo etched ladders as a mount.
I drilled small holes in the pole to fix the ladders with their mounts at the pole.
I added some electrical cabinets and some fake wiring stuff to look like the real thing.
