Snapmaker cooling fan duct updated v9

thingiverse

This fan duct is redesigned to prevent collisions with the printing bed during calibration saving. It performs flawlessly for my printing, enhancing overhangs and adhesion significantly. v9 Update 2019/4/28: The thickness is trimmed for a clearer view of the nozzle and to avoid potential damage to newly printed layers. A small platform is added to fill the gap between the fan surface and the extruder shell surface.
