Open AIr Valve Holder for an Orcon MVS 15R

This design is based on the Open-AIR project by Flamingo-tech. See https://github.com/Flamingo-tech/Open-AIR. This design is licensed under GPL-3.0.
 

The Open-AIR project describes open-source air valves (and valve holders), both hardware and software, which can be integrated into a DucoBox ventilation unit. These valves are controlled via ESPHome and can be operated through home automation systems like Home Assistant. The project also includes valve holders designed for installation between two ventilation ducts.
 

Because I needed a custom ventilation unit due to a ceiling-mounted ventilation opening and had limited space for separate valve holders between ducts, I modified an Orcon MVS 15R ventilation system and adapted the valve holders for direct mounting onto the Orcon box.
