Summary

This is a collar to mount flexible, 5" accordion duct to a drop ceiling or plywood, etc. It screws in to the duct.

The outside diameter is 169mm to allow it to be printable on most printers.

I have added a second model that includes screw hole studs for mounting the collar to plywood or like material.

            <div><p>I used calipers (vernier) to measure the duct and the thread pitch and reproduced it (4 attempts) in tinkercad.</p></div>
