Hinged Extruder Cooler - Anet A8

thingiverse

Looking through things for the extruder cooling fan, I saw a multitude of options. Having an idea of what I wanted to do, I started with a couple of objects I found here that caught my eye. A hinge would give me ready access, but none suited me perfectly. So, I imported some stuff into SketchUp and began working on it. I had already cut the heat sink, leaving the bottom five ribs mounted to the extruder frame in place. This took care of helping keep the heat away from the filament, but I knew I should have more airflow. I checked the heat load routinely with a laser thermometer and it wasn't too bad at all. But, I still wanted to get the fan back up and running. I went through about six iterations of this design before getting something that really worked for me. The bottom portion of the fan mount allows cooling air to reach the heat sink effectively. The brace across the width of the mount lets it sit on the heat sink for stability, keeping everything in place. The upper area allows for plenty of airflow over the filament and gear assembly, letting the warm air escape from the top. Print Settings Printer: Anet A8 Rafts: No Supports: Yes Infill: 30%
