Hello again, I bring you some progress, I have printed the housing and I have started to assemble all the hardware, I had some problems with the PMS module but in the end I could solve it, I am waiting to receive a module to connect the controls.

I finally got the necessary components to mount the PMS and by the way I followed your advice and put a copper plate and modify the ventilation of the housing.
