Ender 3 (& Pro) Part Fan Duct
thingiverse
Release notes: 2019-08-21: New design takes less space and optmizes air flow. =============================================== This is a new duct for part fan cooler to help improve ABS/PLA printing. It has 3 functions: 1) To be simple; 2) To block hotend fan drafts coming from above (hotend air passages and holes) that annoys ABS printing quality; 3) To direct wind over the part being printed (helps improve PLA printing). Suggestion for printing: stand up, with tree support (enable it in Cura experimental settings). Be careful at removing supports from the big hole for not breaking the part up. Any feedback is welcomed! :) Thank you!
