Parametric 18650 battery grid
thingiverse
This is a fully parametric remake of the 18650 single battery holder by digitalkiwi in OpenSCAD. Any size cell grid can be defined with ease. Grids fit together seamlessly to form large battery packs. For added convenience, there's an option to omit the restraining tabs, which comes in handy for the negative side of the battery where defective cells can be easily removed from the pack. A slot is also available for cable ties to secure the pack together or restrain the busbar. STL files are provided for a variety of grid sizes.
