This is a custom wall mount designed specifically for the Amazon Fire HD 8 (2018 model, I think: 8th generation).

I’m using it as a smart home dashboard display for Home Assistant (see photos).

The tablet slides in from the side and is held securely in place. Cable routing is integrated.

No adjustable parameters – it’s made to fit this exact tablet model.

If you’re using the same tablet for your smart home setup, feel free to print and enjoy.
