This GPU sag bracket was designed to fit between any two fans. This makes it perfect for many fish tank cases, but it was designed specifically for the Antec C5. The base secures into the screw alcoves of the fans and brings my Galax RTX 4070 up to the perfect level. The Antec C5 is an excellent case for preventing sag; it holds the GPU very securely, and mine was only sagging one degree, but when dealing with expensive GPUs, it is better to be safe and protect your investment. It also looks really clean and nice. I recommend printing it straight up since the bottom, where the supports connect, will be against the fan. If the height needs to be adjusted, it should be relatively easy to adjust in your respective modeling software. The base plate is 2mm thick, and the support leg is 14.5mm in diameter. This is a very niche model, but I hope it finds someone in need of it.
