Part Fan for 40mm Extruder fans

thingiverse

This is an innovative reinterpretation of ImChris' E3Dv6 part fan design. Initially, I printed the part without realizing the extruder fan was 30mm in diameter, rather than the standard 40mm used on my machine. Removing the undersized fan resulted in some intriguing visual effects, but I managed to restore a smooth flow by incorporating structural elements into the fan itself. Although not a mechanical engineer, I believe the interior arcs contributed significantly to the overall design. Despite being past midnight and struggling to recall the technical term for those specific extrusions, I'm pleased with how the final product turned out. Once it's complete, I'll post a photo of the finished part here.
