LENA Recorder Holder for Multiple Devices

Rather than store our LENA Recorders (http://www.lenafoundation.org/lena-pro/) in a box or a drawer, I decided to make a quick holder for them so they can have a nice place to rest while not in use.

A rectangular solid with correctly sized slots for these devices.

I originally pictured a single charging dock on the front of this, but I have more pressing challenges at the moment.

I keep getting requests to build this with different capacities, so I am uploading them he
