Fits virtually any 52mm (2 1/16") gauge that uses the traditional ‘U' bracket for retention. Gauges with threaded bodies (like Equuis) are not guaranteed to fit or be tightenable. Has a 14x15mm passthrough on the bottom side to allow routing of cables and large connectors without having to drill into any stock ducting.
I have had one installed for over a year now with ZERO whistling, rattling/vibrating, restricted airflow, or any other issues at any blower speed and temperature setting. Glare is also essentially a non issue due to the steep upwards angle. It can catch the sun but is very unlikely if not nearly impossible to reflect it directly into your face.
Any filament should be fine other than PLA due possibility of the ambient cabin or HVAC heater temps softening the plastic. Supports are required. F3D and STEP files included for ease of remix.
You will need a strip of open cell foam such as https://www.amazon.com/gp/product/B00005202U to seal up the duct to vent connection.
