I remixed @Meiji_Black_3253347's Rear Intake Duct for Ncase M2 & NH-D12L to make a rear intake duct for my NCASE M2 build with the Noctua NH-D12L on a TUF Gaming B850M-PLUS WiFi AMD AM5 B850 mATX Motherboard.
Pictures show remixed duct in place, without duct in place, and @Meiji_Black_3253347's model in place. Also shown comparisons between remixed model and @Meiji_Black_3253347's model
Printed on CORE One with Inland PLA+ white with preset “0.15mm Balanced” settings. Did not enable supports when printed with the mounting holes side down and quality was sufficient.
Will probably replace with a PETG or a more temperature durable filament down the line, but as an intake, it doesn't get exposed to that much heat.
The author remixed this model.
Original model is a shorter duct from different motherboard's CPU mounting location. I extended the duct to length necessary for different motherboard's CPU mounting position.
