CTC Prusa i3 fan duct 2

thingiverse

Here are two versions of the CTC Prusa i3 fan duct mixed with a custom design. Simply print them without supports or any other adjustments. Version 3 is an improvement over the previous designs, directing airflow downwards away from the nozzle for better performance. The 5.8 version combines elements of the third iteration with generic fan parts, offering a reliable solution that I'm currently using myself. However, further testing is still needed to refine its effectiveness.
