I have printed this one, it is OK but not durable. You definitely want to print on its side - if the layers are across the direction of flex it won't last long. Unfortunately there's no good orientation, when your buttons are printed for maximum strength the fingers that reach into the mainboard buttons are not and they break off easily. This is a good candidate for remixing to allow a piece of piano wire or plastic to be bonded in for strength in the direction you choose to have the print layers laid down in the short direction.
Maybe something other than PLA or PETG would be a better material here.
