Running short on sources for cells. Not enough to complete another 14 packs yet. May need to consider actually purchasing some. 😞

Hi Paul,

if I understand DC Kiwi well, you can make or have a file to make 3D cell holders. Great if they are dynamic expandable.

Any advice of what best to buy?

I have currently over 800 Samsung 40T and almost 400 Samsung 30T where I want to do something with.

Kind regards,
