meta.frame hotend 30mm fan

thingiverse

Hi there! Since I had a tough time with most fan designs I tried out earlier, I created these instead. The stand part features upper holes that fit perfectly on my hot end - a setup that already works great with just copper wire. My main goal was to design a cleaner and quieter hot end while reducing the amount of dust and particles that tend to build up on other fan designs. One thing that was a must-have for me was ease of access, allowing users to change out the fan by simply removing the entire assembly if needed. As it often seems to happen, fans can die at the most inopportune moments - like during demos or presentations. Unplugging the entire assembly became a significant design challenge. In addition, the angled wings on both sides of this stand do an excellent job of keeping the intake and output away from the hot end itself and directing them towards the platform where the passive cooler resides on many kits. This is my first time sharing a part with you all at Thingiverse after following your community for some time, so I'd greatly appreciate it if you could be kind. Here are my print settings: Printer: * Frame: XL Rafts: * No Rafting Needed Supports: * No Support Material Necessary Resolution: * 0.3mm to 0.5mm layer height, works beautifully in both modes. Infill: * Infill of 80% or more, especially useful for blocking wind. Notes: To ensure minimal air resistance, I printed a few models at both 0.3 and 0.5 layer heights with around 80-100 infill - a configuration that significantly reduced noise while still providing an efficient airflow. Both ABS and PLA prints work seamlessly on this setup when used for printing heads of both types. Even if the fan itself is made from PLA and you plan to use it with ABS, don't worry, there's sufficient separation between them to avoid any melting. Post-Printing: For maximum noise reduction and smooth airflow, ensure all four screws that grip your fan in place are tightened evenly. If the hot end does not have pre-drilled holes for this attachment, copper wire and a bit of patience can work miracles. Always face your stand upwards away from the hot end - directing shrouds to blow outwards instead of inward helps create smoother flow. One important thing: remember to think through the wiring before closing things up tightly; both of my recent installs required repeating steps one through five.
