Besides the walls of the set, we have to model the places where the robot models, in compact form, will be stored. Along with the stands, we will also have to create a few pillars for the structure of the model. If we take a look at the image shown in the previous chapter, we will also have a luminary attached to the pillar.
Start with a mesh cube creation, and scale it up in the Z axis to make it look like the following image (section 1). Select the top face of the cube, and extrude it up a bit in the Z axis again (section 2).
Now, select one of the small faces created with the last extrusion (pointed in the following image), and extrude it to the left.
This is the base model for the stand, which can be distributed in the scene using an array modifier. Add the modifier and set it to create three copies of the object in the Z axis. After that, add another array to create three more copies of the stand in the X axis.
