I have been working on integrating an active grille into the fibreglass partial grille block.
I went the COTS (commercial-off-the-shelf) route as to speed up the construction. The grille vane assembly is from a Chevrolet Bolt, or Malibu ? It includes only the plastic frame, no actuator-motor. It is a generic brand bought on amazon.
I basically cut it half, added a servo motor and a pair of micro switches (top and bottom).
Pretty basic functionality for the time being (OPEN/SHUT), but I will be integrating the micro switches and an LCD display. Below is the active grille block in action.
Stay tuned for more updates in the coming days.
Cheers.
