This just a case for your generic 7 inch display for a Raspberry Pi or whatever your desired usecase is.
I used this specific modell: https://www.amazon.de/s?k=7+zoll+display&i=computers&sprefix=7+zoll+disp%2Ccomputers%2C143&ref=nb_sb_ss_ts-doa-p_1_11 but I,m pretty sure, you can fit other ones into there as well.
The author marked this model as their own original creation.
