BMW E82 N55 (and maybe more) Oil cooler adapter

I upgraded my oil cooler lines to AN with an aftermarket oil cooler housing, but used the stock oil cooler radiator. The radiator has a larger ring on it, and all of the ones I found online fit the cooler housing, but not the radiator. I ended up designing this largely off of all of the available models out there, but with the larger cutout so it can actually clamp the factory O-Ring connectors to the oil cooler radiator assembly. I 3d printed demo models, and made the final product out of aluminum. I would not recommend this as a 3d print unless you have a crazy exotic filament capable of withstanding the 200C+ temperatures
