18650 Battery Bracket Holder System

A modular, Lego-like bracket system for building 18650 battery packs. Snap the brackets together in the shape of your pack, drop in your cells, and stack more on top. Compatible with all 18650 cells, quick to print, and uses very little filament.

Note: fit can vary slightly between cell manufacturers — you may need to scale up or down a percent or two for a perfect fit.

Disclaimer: building battery packs can be dangerous. Only attempt this if you know what you're doing.
