X Max Hotend Fan Duct

thingiverse

First, I'd like to say that I'm part of several social media groups focused on QIDI printers, where I've noticed a common issue: clogged extruders. This problem arises from heat, which radiates from the heat block and creeps up the hot end, softening the filament until it crumples at the top of the aluminum tube. I've attached a photo showing this issue. The factory-designed hot end fan blows air only onto the upper black heat sync fins. While necessary, this airflow is insufficient. Meanwhile, the round and silver "lower heat sync" fins receive no airflow from the standard design. My redesign aims to change that by directing more airflow at these lower fins, which will efficiently remove heat and prevent heat creep and clogging issues. Before embarking on this project, be aware that some alterations are needed to the metal components of the XMAX hotend. These modifications can be made easily with a metal file in just a few minutes. Thanks to my 5010 quiet fan upgrade, I'm now pushing much more air across both the upper and lower heat syncs on my XMAX, eliminating the heat creep problems that were causing clogs on my printer.
