Great design, the curves flow organically and looks like a piece of art. I printed the large size for my iPhone 6S +. Using Faberdashery Space Marine blue filament on a Printrbot Metal Plus. .2mm height and 195C temp, 10% infill. The blue has a silky quality, and changes color slightly as the light hits it from different directions. The green was a request to match a phone. And I was told that to really resemble a sticky note pad, I should make one in yellow. She was right!
