3D model description

I design this model to help me soldering with the spot welder the 18650 battery packs for my Powerwall

The model is designed to support six 18650 cells and be all aligned in high to use the spot welder.

Each cell will have between 1mm or 2mm free space with the neighbor, to have some space for ventilation and do not have contact, I recommend to use some hot glue to give the pack some sturdiness, with just a drop between them is enough.

The bottom allow a nickel strips of 10mm width max.

I added for free to the download an extractor model to help you in the hard work of extracting the battery pack from the holder.
