Today, I have some mechanical parts in preparation for another project. These are stackable 18650 battery holders without electrical contacts. I have some more holders for pure storage and also single (non-stackable) battery holders with contacts, but these are something in between.

Let’s have a look:

I actually ordered two variants of them, and as usual, a seller that has the one type doesn’t have the other in stock and vice versa – or they are super expensive. […]
