21700 Hex Cell Holder 22.7 mm Centers
thingiverse
Cell holder for making battery banks out of cylindrical Lithium Polymer or LiPO cells. This one is sized for the 21700 A.K.A. 2170 A.K.A. Telsa Model 3 cell. It could be scaled by 86% to work with the 18650 cell. These are designed to have 22.7mm centers between cells in all directions, to work with nickel strips that are designed to connect two rows of batteries on 22.7mm centers. They are made to be joined by gluing (hot glue works fine for this). Recommended material is ABS for long term durability.
