SnapMaker Cooling Shroud

thingiverse

This is a shroud designed to complement the bottom fan on the SnapMaker 3D printing module. It utilizes the four screws that secure the fan in place and simply mounts over it. The shroud features a valve that enables you to redirect airflow away from the nozzle for filaments like ABS, which do not require cooling. The valve can also be positioned partially open to reduce the cooling flow when desired. This initial version has a slight misalignment issue with the nozzle and may necessitate adjusting the shroud as the screws are tightened to achieve proper alignment. I plan to address this in the next version. Additionally, I intend to provide the nozzle with more clearance, as some nozzles are larger than the original SnapMaker one. EDIT: 8/12/18 Updated. The shroud now includes housing covers to facilitate cooling flow. Be cautious not to pinch wires when installing the Left Cover, as they should route along the front edge of the housing between the two ribs and the housing itself. The Right Cover Spacer must be mounted on the fan before installing the cover, which snaps over the screws. EDIT 9/8/18 Updated. A smaller, more aesthetically pleasing design has been implemented, providing an improved nozzle view and enhanced airflow. The valve now features an arrow indicating the direction of flow. For optimal cooling performance, fill in the area surrounding the square nozzle holder to prevent hot air from escaping through that opening. The material used must be able to withstand high temperatures; suitable options include brass shim sock, teflon sheet, or mica.
