Stackable beer crate for batteries

I love the original crates (thanks @CAD-Guy ) and have a few printed out, but I didn't have any glue to fix on the base that makes them stackable, so I remixed the original to allow the crates to stack without any additional parts. As you can see from the picture, they lock together well and I can tip the crates over a good amount before they fall apart. I also added the battery type to the crate so I can see what is in each crate at a glance.
