Vortex Fan Duct

This fan duct is designed to direct air in a vortex pattern around the nozzle's tip. This pattern allows for efficient delivery of air to the print from all sides. A 40mm blower fan provides enough air while being small enough to sit next to the motor. This design should work with any extruder mounted directly on a NEMA 17 motor. Only the mount has to be customized for a particular extruder and nozzle combination.

The initial design includes mounts for a Bulldog Extruder, an MK8 M6x26mm heat break, and either a 21mm Volcano nozzle or 13mm V6 nozzle. Please refer to our other design for a Bulldog Extruder Filament Guide: https://www.thingiverse.com/thing:3562567

Preparations:
- Start bed leveling procedure on the printer.
- Measure distance from top of print bed to bottom of carriage near the screws holding the extruder in place.
- Choose a combination of fan duct and mount that is closest to the measured distance, For example, 17mm fan duct + 21mm mount = 38mm. This is the hei
