18650 Battery Spacer
thingiverse
The spacers are for arranging 18650 lithium cells in a square (orthogonal) pattern. Use in pairs with one toward each end. I used these to rebuild a small 6S pack where I just stacked them 3x2 with the spacers and wrapped with Kapton tape. This is a panel of four - break them apart. Suggested mod: put a hole through the center for better air flow. I also have ring type organizers that are more stable but take more space.
