Magnetic 18650 case with tp4056 charging stand

thingiverse

Since I couldn't find a 18650 case that met my requirements, I created one from scratch. Unfortunately, this is an old project that I didn't document thoroughly. If additional documentation is needed, I apologize in advance. This project took several weeks to refine, with numerous failed attempts and a significant amount of filament used along the way. Here's the finished product. If you find my project useful, please consider showing your appreciation. To create a tutorial video, I'd be happy to do so if there's sufficient interest expressed. With the stand facing you in this orientation, you can see the TP4056 charging circuit. Clip your 5V connection to the left copper leads, and your protected output will be on the right side. One thing I like about the TP4056 is its simplicity as a UPS - so you can use it while charging. However, please don't quote me on this; consult an electronics expert before using it with your batteries.
