Airconditioner duct screw lock collar

Liked the idea of original model, but it was designed to be screwed in place. I needed to be able to disaassembly the mount on demand as it's a mobile airconditioner without any permanent wall hole.
Inspired by the other remix source model, I've placed a board within the window. Not translucent but plywood with reflective foil to minimize heat coming inside. Hose mount lock is screwed into the board which has paths guiding the rotation.
