About this model

Just a simple nested spacer made for 21700 cells in 6S2P nested configuration (or really any 12 cell configuration). Intended to add a little fixed structure in case of a crash / the cells getting hot enough to melt the hot glue used to tack it together. Step file included if you wanted to chamfer the edges. Cell used in this were Molicel P42A - hopefully it works for other cell types.
