Monoprice Ultimate Blower Duct

New Easier To Print It's finally here, the update to the duct work that should resolve some of the printing issues many folks have encountered with it. The new design still maintains its structural integrity, holding its shape when printing, but now requires significantly less bridging to complete a print. You'll still need to rotate it 180 degrees on either the X or Y axis and print using support from the bed only. Dual Fan Version After much anticipation, I've made good on my promise by adding a dual fan version of the duct, along with a mounting brace. This new design includes an additional 4010 fan for enhanced cooling capabilities. Please note that this doesn't mean you need it; in fact, I believe the single fan version with an upgraded fan is a superior upgrade due to reduced weight on the print head. However, for those who desire more fans, there's now an option available. Note the small pegs on the mount align perfectly with the access holes for the linear rod bearings, and there's a convenient cutout on the inside face that fits a small 3M Command Strip perfectly, securing the brace in place. I'd love to see this installed on your printer and wish you good luck with the installation. Original Comments Several dual fan blower assemblies have been seen for the Monoprice Ultimate / Wanhao D6, but they all seem to add unnecessary weight. This design is based on ring ducts found on other printers/extruders and appears to do a great job without the extra weight. One potential modification I might consider would be to slightly increase the diameter of the duct for more clearance around the heater block, allowing you to print it in PLA without worrying about sagging edges that could collide with your prints. Otherwise, I'm quite satisfied with this part. A new design has been added, increasing the ring diameter from 60mm to 70mm. After a couple of days of use, my concerns about the ring sagging and colliding with prints proved well-founded. The larger design in PLA continues to perform well even after extended use, while the smaller diameter design remains available for those willing to print in higher temperature materials who desire closer airflow. A third design has been added, featuring a full ring and a more square profile. These features are intended to make the ring more stable when hot and prevent the duct from drooping into prints. Additionally, by removing directional vents and adding more outlets, this design provides a larger cooling area that seems to work much better. I'd greatly appreciate your feedback and suggestions. A quick update is in order. A couple of Thingiverse users have pointed out that printing this part "upside down" yields better results. They're absolutely right; turn the duct over so the fan port is oriented downwards in your slicer to reduce support requirements and improve overall print quality. Thanks, EasySt, and others who brought this to my attention. Print Settings Printer: Monoprice Ultimate Resolution: 0.1mm Infill: 20%
