CR10 OEM fans ducting improved

thingiverse

Here is a rewritten version of the text: I printed this design in PLA as a solution to printing issues on my CR10 without having to purchase multiple new components. The project was inspired by Thingiverse's 2544186, which was itself a remix. I printed it initially but couldn't fit it due to tight tolerances around the heat sink. This led me to redesign from scratch with two main objectives: 1. Improve airflow through the main cooler design by allowing air to pass in and around the heat sink rather than trying to force it through, while also enhancing mounting surfaces. 2. Create two separate parts that slide into each other, enabling users to modify one part without reprinting both, as ducting designs often vary according to user preference. The new design works well even with PLA, but I'm planning to test an alternate duct end design once I have access to more advanced printing materials. I've included the original Fusion 360 archive for anyone looking to customize it further if needed. UPDATE: After experiencing more problems and conducting temperature measurements, I remixed my remix again. This time, I modified the heatbreak cooling system which, despite its initial intention of improving part cooling, proved less efficient than the original steel box. The updated design allows for a 10-second reduction in cooling time from 200°C to 100°C compared to the original steel box. Part cooling was already improved, so no changes were made there.
