A fully 3D-printed, open-source power bank that turns a simple idea into a hands-on making experience — built from scratch, shared open source for everyone to recreate.
Description
The 4-Cell Open-Source Power Bank is a fully 3D-printed power bank designed and built entirely from scratch. It’s compact, practical, and powered by four lithium cells — a perfect example of how digital fabrication and hands-on making can bring an everyday idea to life. Every part, from the body to the internal structure, was thoughtfully designed for function, durability, and ease of assembly.
Open Hardware for Everyone. In the spirit of open-source making, all design files, electronics schematics, and assembly guides are freely available for anyone to download, modify, and recreate. Whether you’re a maker, educator, or curious beginner, this project invites you to explore, build, and learn by making something truly useful — your own custom power bank.
