<p>This is a very simple tool, but also very handy, so I decided to share it.</p><p>It fits 3 cells of 18650 size and squishes them together to waste as much space as possible. I've used it for spot welding tens of them and it helped me save a lot of time.</p><p>Also adding a piece that helps with wiring - use it as a “plug” when heat-shrinking the battery pack.</p>
