Not my design. The original is called Sun Medallion by profhankd on Thingiverse.

The model can be scaled up or down but if scaling down, ensure X and Y are even and Z is half. So if scaling down to 50% length/width, then scale height down to 75%. The gold sun was printed with Bambu Lab Silk+ and is scaled down to 25% x/y and 50% z. It's also worth noting that concentric top layer may look better, adjust as needed in your slicer.
