Prusa Fan Ducts

thingiverse

This setup showcases the input and output paths for a Prusa extruder fan. It is inspired by ncbob's "Duct for 40mm Fan for Greg's X-Carriage" design. Originally, the fan had vanes that dispersed air onto the print bed, affecting adhesion. The duct length to the extruder was shortened and angled upwards. A top-drawing input fan shroud was added, which also clears the z-axis lead screw.
