Based on the excellent model by KalleKnall, the following changes have been made.
The aim was to supply the electronics with fresh, cold air from outside the printer housing and to transport the warm exhaust air back outside. In addition, brackets for WAGO terminals have been added to make it easier to wire lights, fans, temperature sensors and so on (rails for 5 volt, 24 volt and ground).
