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

thingiverse

Greetings, This is a replacement hotend fan shroud designed to significantly boost layer cooling for cleaner printing with PLA, PETG and any other filaments that benefit from extra cooling. My primary objective was to develop a shroud design allowing for symmetrical cooling from both sides of the nozzle. Due to space and weight considerations of the compact hot end/cantilevered X axis and the limited air pressure generated by 40mm fans, I have arrived at this design as a temporary solution. This project is still very much active, so please test and comment. Future iterations will explore dual fan and cage fan options. Here are two fans I recommend: The 40x20 version is quite loud but extremely effective: 40x10 http://amzn.to/2em3zOk 40x20 http://amzn.to/2e6MNUO Update: Ran through STL repair for potential S3D issue. Default orientation is now the simplest way to print, no support required.
