3D Mars Sign at NASA Space Center

Building 3D letters to create a free standing sign for the MARS public exhibit at NASA Space Center.
We went a different route for this project. We used premium marine grade lumber pressure treated to survive complete water submersion without rotting or warping. It also added a lot of weight so they could free stand in the grass in front of the outdoor exhibit. Next it will be coated with an industrial grade epoxy that will make them practically bullet proof and last forever. The sign will be anchored to the ground with steel pipes running into the ground internally.
