A queue type case for transporting 18650 cells for vaping. Handy for keeping cells in order to prevent over working any cells. Tested with LG HE2 and HE4, Panasonic and UltraFire cells. Old UltraFire 2600mAh cells are too long. Newer UltraFire 3000mAh cells are fine.

Requires 4x M3x20mm screws and nuts. Print two copies, drill out the thin layer in the screw holes, and bolt together. Presto!
