Remix of my Noctua Fan mod: MP Mini Select 3D PLA & PETG 40mm Fan Shroud (http://www.thingiverse.com/thing:2250288) which is a remix of MP Mini Select 3D PLA & PETG 40mm Fan Shroud (http://www.thingiverse.com/thing:1676718) that can be used for the Noctua Fan. I highly recommend the original design, especially for 40mm fans with a thickness of 1cm as they produce less pressure and minimize backdraft by directing air downward. Modification of original design: 1) The shroud nozzle has been extended by 3.5mm to potentially direct more air onto the print. 2) Larger holes are included to accommodate anti-vibration mounts (brown mount in photo). However, only two holes remain available for use. 3) The notch where fan clips attach has been improved, eliminating the need for supports. Proper alignment of the shroud is crucial due to its slight height increase over the nozzle. A small amount of blowback may occur, but I believe this is offset by increased airflow on the print. Ultimately, it's up to the user to decide. Warning: Due to tight clearance, unintentional artifacts from initial layers or stringers may cause the shroud to collide with them. Be cautious when printing. As with my original remix (http://www.thingiverse.com/thing:2250288), I have included a noctua_plug.stl file that should be seated in the two unused holes of the fan. These plugs help reduce air leakage. Extra files, noctua_screw_nut.stl, are provided for users who want to switch between different shrouds or prefer not to use anti-vibration mounts (print two). However, keep in mind that these screws will sit lower than the mounts and may cause the fan's back end to rise. To minimize air leakage, consider applying masking tape around the seam. Print Settings: Printer: MonoPrice Select Mini Rafts: No Supports: No Resolution: 0.13125mm Infill: 50 Notes: Brim may be necessary for screw/nut & plug. All objects in STL are print-ready orientation. Post-Printing Alignment of shroud is essential due to tight clearance.
