Fractal Flower

This model is a fractal (iterated function system) created to resemble a flower. Through post-processing, I've made it 3D-printable. I used PLA with a .4mm nozzle, a .2mm layer height, and 10% infill. With PLA and adequate cooling, you shouldn't need supports. You might get better quality prints if you reduce layer height and extrusion width (and/or nozzle size).
