Does anyone have CAD models of the Dayton H6512 / Pyle equivalent (JBL waveguide clone)?

[AwesomeSauce2015]

Pretty simple question. Does anyone have a CAD model of this waveguide, or have one and would be willing to make a simple model that shows the internal geometry?

I've been wanting to experiment with adding midrange ports to it, so that I can use a higher tweeter crossover point and still have good directivity. But, without a CAD model I can't simulate the waveguide in AKABAK or Hornresp, and I don't want to buy something if it isn't going to work.

Despite my best efforts, I have not been able to find a CAD model of this horn. Surprisingly, even Parts Express support doesn't have the models. So does anyone have one?

Alternatively, has anyone already tried turning this waveguide into a unity / synergy horn type unit?

Have you tried the DIY Audio forum? You will have more chance there. I know DonVK has simulated many waveguides in AKABAK and the above horn might be one of them with a CAD model.
