Hey there! This is my first big project. I looked at many battery holders/storage and none of them met my needs. I wanted storage for 8 batteries that I could easily and quickly spot on my desk, something colorful. The first iteration was an egg-like box but that didn't print well and all attempts at using supports made the surface look horrible. So I re-designed and re-designed, from the box becoming cube-like, to relief becoming flat vectors, to round pins becoming triangle pins.
