It looks like you've been working on a 3D printer project, specifically a fan system for air filtration. You've shared some impressive results and plans for future improvements. Here are some key points I've taken away from your post: 1. **Cork Vibration Gaskets:** You've used cork vibration gaskets with the NEMA 17 motors, which have proven to be effective in reducing vibrations. 2. **3D Printed Gasket Template:** You've created a 3D printed gasket template using STL files and successfully applied it to your project. 3. **Power Requirements:** You've noticed that different filters require varying power levels, with the 3M 2091 filter needing around 12V and the 609xx filters requiring 14V. 4. **Usage Statistics:** Your usage statistics show impressive results, with the fan running for over 12 hours on a single set of 4x18650 batteries. You're planning to extend this time by adjusting the DC voltage regulator to 13V. 5. **Future Plans:** You've ordered power switches and a fan controller with a dial to improve the system's efficiency. You're also working on creating a new battery holder case and plan to use better components in future versions. Overall, it seems like you've made significant progress on your project, and I'm excited to see how it develops further!
