Noctua Fan mod: MP Mini Select 3D PLA & PETG 40mm Fan Shroud

Human: Remix of the MP Mini Select 3D PLA & PETG 40mm Fan Shroud (http://www.thingiverse.com/thing:1676718) suitable for the Noctua Fan. I believe the original design is excellent for 40mm fans, especially the 1cm thick versions that produce less pressure and have reduced backdraft with this design as the air flows downward. The modified version of the original design features larger holes to accommodate anti-vibration mounts (brown mount in photo), while still maintaining two available mounting points. The notch where fan clips attach has also been improved, eliminating the need for supports. Additionally, the noctua_plug.stl file is included, which are intended to be seated in the two unused holes at the far end of the fan and may help reduce air leakage (two prints required). Furthermore, the noctua_screw_nut.stl file provides a skew/nut that can be used as an alternative to anti-vibration mounts, particularly useful when switching between different shrouds. However, please note that using this option will cause the fan to sit lower than the mounts, potentially causing back-end clearance issues. To minimize air leakage, users may apply masking tape around the seam as shown in the second picture.
