Custom Fan Ducts for CoreXY 3D Printers - 30mm and 40mm Blower Fans Upgrade your custom CoreXY 3D printer with our precision-designed fan ducts. These ducts are specifically crafted for 30mm and 40mm blower fans, ensuring optimal airflow and performance. The 30mm fan duct is designed to work seamlessly with standard V6 hotends, while the 40mm fan duct is tailored to fit Volcano hotends perfectly. To ensure a secure hold, print these fan ducts in materials that can withstand high temperatures. We recommend using heat-resistant filaments such as ABS or PETG. Update: April 2020 - Small Fan Duct Revision After testing with resin printing, we identified two key issues that affected the original design. Threaded inserts sometimes failed to seat properly due to material shrinkage, and clearance problems arose when assembling the fan ducts. To resolve these issues, we downsized the bolt holes to allow for direct threading, ensuring a more secure fit and improved performance.
