The complete rack (for 3 devices) consists of 5 parts which I glued together.
For the first (lower) device there is only one part (red in drawing). The second (middle, yellow in drawing) and third (top, blue in drawing) has two parts - one for the lower and one for the higher part.
You can choose if you only want a stand for one, two or three devices.
The author marked this model as their own original creation.
