7" element 14 Raspberry Pi touchscreen, untethered

This is a way to use the Raspberry 7" touchscreen without having the Pi control mounted on the back, so you can have the control in the back of your printer with the relays but have your touch screen ware you want

Regular 7" pie touchscreen display but no raspberry Pi mounted on back, I was able to use standard 5v 2.5a power supply micro usb, And used a Adafruit Flex Cable for Raspberry Pi Camera - 24" / 610mm. And works perfect, Problem i have is cant find no display case without the raspberry Pi attached to back.
