This is a small bracelet representing a chain of hearts. I printed it in its original size using Ninjaflex filament in flamingo colour but the end result was not showing the details very well and was not very comfortable to wear. I recommend printing it larger than original size.

Using Ninjaflex filament, it is very difficult to remove the supports. I had to use fingernail clippers to separate the supports because scissors and knives did not work.

I needed a small model to experiment with Ninjaflex. I started by sketching a heart. My first few sketches did not look right (they looked too much like a triangle and two half circles). Once I realized that I needed to overlap the half circles, I settled on a shape. I extruded it and then made some sort of smarties/m&m shape that I subtracted from the heart to make it concave. I then smoothened the edges and made four copies. I individually rotated each heart on two axes and overlapped them until they looked just right. In the end, I sketched a circle of the desired diameter and repeated the four hearts in a circular/path pattern around the circle.
