I do not believe that Amazon is spying on us, but there are a numerous hackers in the world. And, getting dressed in front of a camera….
This privacy shield is for the Amazon Echo Show to cover the camera. It will put the device to sleep because it can not detect movement in the room. You can still access the three buttons on top of the device with the shield installed.
The Camera is in the top center of the device.
I put “Alexa” on the shield because that is the wake up word for the AI.
This gadget was made with Tinkercad, and is published on Thingiverse and YouMagine.

There is news that Alexa is randomly laughing 😂
Alexa randomly talks about many things. The privacy shield puts her to sleep, so she is not talking to the TV as much.
