The display that was used in the images, was listed down below.
you will need to either cut the back of the display housing or remove it fully (not recommended, hot glue can rip out the necessary components out of display when trying to mount the raspberry pi 4 itself cutting the back housing as required, any time in future I will make v2 of the case where original display housing won't be necessary)
The author marked this model as their own original creation.
