Source for Cassette racks
 

Building a spinning vertical rack to hold audio/video media for the
IL's.

Having trouble finding a vertical rack to hold cassettes horizontally.

So rack goes up and down and cassettes lay flat in slots

The sources, Rockler, Woodworkers Supply, Lee Valley, all have short
racks instead of a long tall one, and they are not recommended for
vertical orientation.

Other sources out there?
