Aluminum Fire Ant Colony Cast #070 - Base Picture.
The display base without the cast. The 3 risers must be in contact with the cast in specific places for it to sit correctly on the base. There are paint marks on the riser supports to help with that (blue on the left, red on the right, and black on the back). You can also see that the top of the risers get scuffed up a bit from the cast sitting on top of it.
