Lens adapter for 72mm Sony lens

I wanted to do timlapses from my window early in the morning. Due to light from the room (and the outside through mirroring) this does not work as reflections and sunglare, etc. ruin the shots.

The adapter ring for this 72mm sony lens (24-240mm) can be glued to a simple (black) cardboard construction. This allows you to take pictures without glare and reflections.

One might think that the entire shape could have been printed - and yes, that is correct - however - the cardboard is better for absorbing the scattered light than the 3D printed material.

1. The original lens hood generator doesn't seem to work for 72mm and up. 
2. With 72mm the “coding” of the three plastic rings is off and makes the result useless. This fixes this.
3. It furthermore adds a base which can be glued against cardboard to allow adding light absorbing materials.
