This is two halves to a Raspberry Pi Kiosk system that supports a 10" Display. https://www.amazon.com/Raspberry-Inch-Touch-Screen-Touchscreen/dp/B0776VNW9C and a fixed barcode scanner https://www.amazon.com/Symcode-Embedded-Barcode-Scanner-Portable/dp/B07CHJX2FB Makes a great time clock!

Note: the support brackets will hold the display onto the box (after you superglue it together) from the inside. Print two of them. The stand offs that come with the display are the perfect length. Use medium length ones on the back of the display electronics and the long-length ones on the far right side of the display. The Pi can just sit in the back.

Note 2: The 'top' of the mount has a tapered wedge to hold it onto screws in the wall.
