18650 Battery Stand/Station. Friend ask me to design something they could use to hold batteries before and after they are charged so that anyone in the house can just grab one if they need them and so he's just not leaving them lying around all over the place. It can also be hung on a wall using standard drywall screws. Haven't had a chance to print the whole thing yet but test printed the cylinders to verify their inner diameter was correct with enough space to also work with wraps.
