Tweeter Horn

This is a tweeter horn with 1 3/8"-18 thread to fit Motorola/CTS Powerline KSN1142A piezo tweeter. It is based on a 3D model of a tractrix horn that I found here: Tractrix Horn for Tweeter. The model is scaled and modified to fit this tweeter. It is NOT a pure tractrix curve - I manually fit the curve using four different conic curve profile sketches in Fusion360. I'm new to 3D modeling and printing, so this is an attempt to learn.

This is the first part of a project to experiment with specific ultrasonic frequencies, meaning that I'm not really interested in multifrequency sound quality as heard by a human ear. The goal is to eventually build a frame for an array of eight tweeters, four by two, possibly offset by a few degrees, in as small a frame as possible.
