This is the logo of the video game Riven, which stands for the D'ni number 5. I simply created this by using a picture of the logo and converted it into an object.

The edges of the object are not really smooth and get more uneven the more you scale up the object, which was the intention as it gave a bit more of an used look to it. I will however work on a cleaner version of it.

Scale the object up or down as you see fit. No support is needed, and use infill to your own liking.
