3D printed Beolab-like waveguide for compression drivers

I noticed that Patrick Bateman had a high opinion on the Beolab waveguide. It looks easy enough to draw in 3D and print. I would like to try it with a compression driver. What would be some good dimensions to start with? What will be the usable frequency range? For directivity, I would like to start with 90 degrees. I wonder how the mini-klam would compare to that.

love to have a pair for 1" CD. Regarding the 3" size, might this cheap Lavoce 3 work w/o contouring ?

(hey Pelanj not on forums for some time as was in the hospital a month from angioedema of the tongue plus picked up infections there in blood, urine, lungs - still real weak/rough/congested - have PEG tube and trach for unknown time plus tongue still has some swelling.)

It looks like a nice project - do you have a thread for that?

Hey Freddi, glad you are back and I hope you will get better soon. I got my own 3D printer, so when the time permits, I will try this out, too. And when the weather will be warmer, I will try to do some proper outdoor measurements of the waveguides I have.
