This is a deliberately approximate (i.e., artsy and presumably not copyright infringing) 3D interpretation of the Sun image seen in the movie Tangled. The STL version here is large -- about 160mm diameter. However, it's only 9.25mm tall, with an interesting 3D contour. The flares are also tied to the center so the whole thing hangs together.
Straightforward print in PLA, but large -- make sure your bed is level. The STL file prints in under an hour on my M2, using about 30g of filament to make the 160mm wide by 9.25mm tall medallion. That size is good for a wall-mounted medallion; shrinking the XY dimensions makes a more viable little medal for a necklace or other uses.
