Raise3d Pro2 Fan Cowl to Help Reduce Heat Creep
thingiverse
A fan cowl to help increase air flow. Use in combination with the other fan mods to try to get more air through and over the extruders to prevent heat creep with PLA and other heat sensitive materials. This design allows the fan grate to sit inside the cowl. Stock screws work just fine. Be careful not to over tighten them though as there's only a few millimeters of engagement if you're going into a 3d printed fan duct. (the stock one is fine it has brass inserts).
