P1P Chamber fan shaft / Chamber temperature control

This shaft is not perfect, but it is a basis for further development.

The bay is designed to use a "Noctua NF-A9x14" fan and a DC-DC converter.

For the temperature control I used this module.

As already written, the designs are not perfect and any further development will help to find a good solution for the P1P.
For the mounting, interventions in the back of the printer are necessary!
Therefore, it is only about the ventilation duct and the bracket of the temperature control!
Who knows something about electrical I do not need to explain the installation and who is not at all familiar with the intervention in the printer electronics, I do not want to explain this, because I do not want to be guilty of a defect.
