Lucky 7 Fan Duct Assembly Upgrade for the Ortur-4 3D Printer

Here is a one piece duct fan upgrade for the Ortur-4. This assembly is designed to accept a 24v 5015 blower fan and will significantly improve the quality of your prints.

Although bolt/nut holes have been provided, the assembly works perfectly without the need for any as the blower snaps into the assembly. Once the 5015 is wired and substituted for the stock fan, the whole assembly is designed to use the geometry of the existing extruder nozzle shroud to snap into place and lock firmly.
