Hybrid annular fan duct

thingiverse

To improve airflow in Murat's design, I combined my Gijs fan duct design with the original. However, be cautious as it can get hot enough to warp if printed in PLA; using ABS is recommended for better performance. Despite being flexible during printing, ABS fan duct seems durable. An update reveals that ABS handled overhangs better than PLA and minimal base warping occurred. A proper fan mounting solved the issue. The ABS version has been functioning well for three months with no issues, provided heater cartridge placement is correct. For printing, use 0.16 layer height, 0.5 layer width with blue PLA, but ideally, print it in ABS for optimal results.
