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. Framing
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. 3D-Construction
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! Top mount
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. Pole cover
I soldered thin brass wires to these photo etched ladders as a mount. Ladders
I drilled small holes in the pole to fix the ladders with their mounts at the pole. Ladders
I added some electrical cabinets and some fake wiring stuff to look like the real thing. Electrical stuff
These brackets are for the lights. Lights
Light brackets in place, but without LEDs so far. Lights
First LED is glued in and still working - only five more to go. Lights
Completely cleaned for painting, LEDs covered with tape. Lights
Airbrushed with Vallejo primer and now drying for at least 24h. Lights
The billboard got a weathering with a white wash first followed by a black wash. The big ads where fixed with a removable foto glue. Finished billboard
Last step was adding the cow with some rods in her legs. (Picture taken free hand via tablet under normal room lighting.) Finished billboard
