CR2032 battery container

The battery is fixed in the container and won't fall out

But what I don't like is, firstly, the complexity of printing, and secondly, the fact that the container only closes with friction.

In this in-depth improvement, these shortcomings have been rectified.

There are options for 10, 15, and 20 batteries here.

Suitable for 0.4 nozzles
When assembling, it's best to use strong glue to stick the lid to the container.
