Self-Adjusting Water Lily Coaster

A coaster designed to look like a water lily, which intriguingly self-adjusts to collapse the inner petals around the object you place on it.  

Print profiles for three different sizes are provided (12 cm wide, 14.5 cm wide, and 17 cm wide), and the model is essentially print-in-place.  So, the only assembly required is to simply place the plate on the coaster, aligning via the provided notch.
