Material & Construction
This battery box is 3D printed and assembled in-house using PETG, a polymer known for its durability and elasticity. All components are printed except for the latch and lid pins, which are added for reliable closure and long-term use.
Use Case & Limitations
This is a light-duty storage solution designed for organization—not a molded, duty-rated product. Due to the nature of 3D printing, minor cosmetic variations may be present and are considered normal.
