DIY Magnetic Li-Ion USB Battery Charger Based On TP4056 - 18650 & More

The TP4056 charger box comes in several STL files, each designed to accommodate the various components of the board. Printing the box with supports can be a challenge, but it's worth the effort to get the desired result. The TP4056_Box_No_Cables.stl file contains just the box itself, with a single hole for the micro USB connector. However, this design requires you to drill additional holes for the wiring, which can be time-consuming and frustrating. For those who need to mount magnets on their TP4056 board, there are two STL files available: TP4056_Magnet_Holder_bridged.stl and TP4056_Magnet_Holder_bridged_deep.stl. These designs provide a hole for an 8mm x 1mm magnet, making it easy to attach the magnet holder to the box. Another design worth mentioning is the top lid of the charger box, which comes in two versions: TP4056_Whole_Lid.stl and TP4056_Wholed_Lid.stl. The former has no holes at all, while the latter features holes for cooling purposes. Last but not least, there's the TP4056_Magnet_Holder.stl file, which contains a magnet holder without any bridging or wiring holes. This design is perfect for those who want to add a simple magnet to their board without worrying about drilling additional holes.
