Waterblock Bracket 50mm base

so i was looking on the net to grab a watercoller for my gtx660 cuz after all these years i finally found an exact copy of my old card. but the thing is that the first card was choking the second one to death cuz they were to close and the fans couldnt breathe. lack of luck my card is too old and only generic watercoolers can be installed on these. so scavenging the parts bin i found those 2 aluminium blocs that i ordered from ebay ages ago and decided to desing this bracke to hold it on my gpu.
