Infinity X1 3D printer fan duct enhancer

This is designed for Infinity X1 3D printer. A little thing could focus more wind to object and enhance wind speed under the same fan speed setting. So that you can decrease fan speed to get lower noise and avoid hotend to be cooled.

No glue or screw needed. Just directly plug into fan door. Easy and effected. Notice the tunnel angle is designed lower side is bottom. Wrong up side down will cause wind direct blow to the hotend.
