40mm Wanhao Duplicator i3 Cooler

thingiverse

This is a remix of a 40mm cooler from here, The original had some major flaws that I felt needed improvement right away. It would frequently snag on parts of the print that had curled or were higher than the rest of the print, hard enough knocking prints lose or the printer out of alignment. This was a major issue that needed to be addressed. It was also somewhat weak where it would mount to the gantry, which made it unstable and prone to breaking. I took the design and remixed it to make the bottom slope away from the cooling ring, preventing any chance of snagging altogether. I also changed the angle of the fan to 45 degrees and reshaped the tunnel to better direct the air flow. This improved airflow allows for more efficient cooling and reduces the risk of overheating. I also added additional support material to make the part more sturdy and reliable. To achieve this, I printed with support touching the buildplate so that the sloped part was fully supported. Once printed, I removed the support and sanded the slope down some to smooth it out. Enjoy!
