Shure SB930 battery holder to transport in hard briefcase

This is a battery enclosure to put in a briefcase and make it easier to transport and store. 

We need to transport more than 30 batteries everytime we use them, so i was looking for a proper way to store and transport, and came to this idea with a cheap rigid briefcase we had around here.

I made tree different pieces, to be able to start and end each row with a flat surface.

I can store and transport 38 batteries in my birefcase.

You can print withouth supports and with big layer size, it should work withouth any troubles.
