This design was originally made by vjapolitzer here on YouMagine for their Mini Kossel. (https://www.youmagine.com/designs/blower-fan-mount-for-mini-kossel-effector) I edited it in tinkerCAD so It would work with my NFire 1 3D Printer. It works great and provides the cooling required. I printed it in different orientations at 0.2mm layer height and 100% infill with support and brim enabled.
