18650 Simple Enclosure (Storage Box)

As a 3D printing enthusiast, I have quite a few lithium batteries, of which 18650 and 21700 are the most common.In order to prevent the risk of short circuits, these batteries must not be directly scattered, so storage is essential, and when there are multiple batteries together, they can be placed in a beautiful and sturdy multiple storage box.But sometimes we just need to carry one or two out of the sporadic one, or one or two more sporadic ones, then what you need more is a simple, practical and beautiful single battery storage box.So I designed this 18650 simple shell (storage box), I am quite satisfied with myself, I hope you will like it too :)作为一个3D打印爱好者，我有不少锂电池，其中18650和21700是最常见的。为了预防短路带来的风险这些电池肯定是不能直接散放的，所以收纳必不可少，当有多颗电池在一起时可以放置在漂亮且结实的多颗收纳盒中。但有时我们只是需要携带零星的一两颗外出，或者多出来了零星一两颗，这时你更需要的是一个简约实用且漂亮的单颗的电池收纳盒子。于是我设计了这款18650简约外壳（收纳盒），我自己挺满意的，希望你也会喜欢:) Key features:1. Simple, very small in size, only one lap larger than the battery itself, with less than 5g of material2. Stable, the tightn
