3DBenchy GPU riser

Graphics cards got heavy, needed a riser. There were some fun ones (the marble column, Atlas, etc), but none quite worked for me. I measured the distance from the bottom fans to where the GPU would need to be, and used benchy scaled down to the right height. Some modifications include filling in the chimney for extra strength. If for a similar setup you will probably want to scale to get the right height. Printing wise, hopefully goes without saying that anything works, but you probably want PETG for a bit of resilience with temperature. I also went transparent to work with the LEDs and make it more subtle.
