Made based off the backplate file provided by BTT, made sure it had clearance with the enclosure panels while not sticking out too much on the outside. In my case I wanted it mounted on the left side, mirror the model to place it on the right side. Only needs heat melt inserts for the screws, and either a 1.5mm printed washer or a couple of m3 washers on the 2 bottom screws to compensate the void left for the original bracket.
