Elfbar Powerbank

This is a project to recycle those resource intensive one time use Elfbars. This case should fit 30 of the harvested cells, delivering around 10800mAh. For charging I used a cheap AliExpress Board (https://a.aliexpress.com/_EG0lWBN) and for wiring some thin gardening wire. I included the step files to extend or reduce the capacity for your own needs.
!IMPORTANT!
Make sure, the opposite poles are never able to touch each other, otherwise you will get a hardly extinguishable lithium fire!!! This is also very important during soldering.
You do everything at your own risk, this is by far not perfect and still work in progress!

Additional things you need:
4x M3 heat set inserts
4x M3 20mm countersunk screws
gardening wire (0.6mm)
some tape (kapton/insulating)
hot glue
