simple 18650 solderless battery housing

thingiverse

Unlike other methods of connecting 18650 batteries such as spot welding or soldering, this approach is non-permanent and won't damage cells, requiring only a 3D printer and nickel strips. I've included STLs for the 5p configuration, negative lids, positive lids, and single cell holders, from which you can create any setup you desire. Alternatively, you may wish to download your preferred format using this link: https://a360.co/2Umkqno (single cell), or https://a360.co/2UBPTSN (5p cells). Don't use PLA filament for this as it may melt if the batteries get hot.
