This is designed to fit over the metal top rail in our office cubical s. I adjusted it to fit our cubical exactly, so some adjustment might be required for different manufacturers.

Pretty simple to print, print it on its side with no supports.

This one has a logo on it, but that is fairly easy to remove or replace with your own.

I designed it to be configurable, but I did not put in the extra work to make it nice for the configurator.
