Ender 3 CR-10 anti collision fan mod set

thingiverse

I design a custom fan mod for my Creality Ender 3 CR-10 printer. I successfully printed it on my own Ender 3. I tried out another fan mod, but it kept hitting the bed clamps when printing large objects. This issue prompted me to create my own low-profile fan mod with minimal material usage. Another challenge I faced was air escaping from the heatsink cooler to the bed. To solve this problem, I designed a cap to redirect airflow towards the heatsink, which has proven to be very effective! I printed the hotend fan duct using PLA and the cap in PETG due to its proximity to the hotend. The fan duct performs well, but the cap begins to deform as it touches the silicone block. To resolve this issue, I plan to print the cap with a more heat-resistant material. This upgrade barely leaves any noticeable difference in the machine's overall performance.
