This project provides 3D printable waterproof protection boxes for your batteries (18650, 21700, AA, AAA, etc.).
**The unique feature of this design is that it is specifically designed to be printed entirely in TPU (flexible filament).**
Because the material itself acts as a seal, the box integrates a "double radial seal" system (ridges and grooves) directly into its geometry,
eliminating the need to buy and add external rubber O-rings.

## **🌟 Features**

* 💧 **100% TPU Printable**: No external O-ring required. Waterproofing is achieved by the compression of the TPU itself.
* 🛡️ **Integrated Double Radial Seal**: Two compression rings on the flange guarantee an impenetrable barrier to water.
* 📏 **Universal and Parametric**: Use the Ope
