Da Vinci Extruder Mounted Fan Duct

thingiverse

This is a mounting system for PLA-style cooling fans intended to be mounted directly onto the back of an extruder stepper motor. Designed specifically for use with a 50mm fan, it directs air flow under the motor towards the nozzle. Two versions are available: v001 and v002. While v001 works perfectly with certain configurations, users must take into account their printer's specifications to ensure compatibility. Notable print limitations include potentially weak bridges that may need extra support during the printing process. Successful examples can be found in systems utilizing fan integration within closed environments, like desktop computer cases. Printing requirements include placing the large flat surface of the part downwards. This particular component requires precise fitting onto the back of a stepper motor via snap-fit installation; however, this feature is not tested and its effectiveness on print quality remains uncertain. Despite any potential benefits to print quality, direct impact assessment was difficult to establish. Standard procedure suggests installing wiring together with extruder cable connections. Mounting an electrical switch near printer components allows for easy access and safe operation. Typical guidelines indicate keeping the cooling fan disabled during initial layers and activating it thereafter. In retrospect, the usage of a 50mm axial fan proves suitable as an impromptu choice based on readily available options rather than optimizing for air flow pressure through small ducts. Centrifugal blower fans represent a preferred design approach, leveraging enhanced performance to push cooling air effectively.
