Those who sometimes look at the project probably notice how my design thought rushes about.

It can be said that with the tree I did not achieve the goal, and although this approach is possible, it is not the most optimal one.
Now it occurred to me to make all the controls in the form of a monoblock, which can be embedded in panels made of wood and other solutions.
The design of the monoblock is based on aluminum pipes.
Aluminum pipes are cut with a pipe cutter, easily and accurately, and fastened with a 6mm diameter screw rod.
