Create a unique bracelet based on a pattern you draw. The pattern is cut from the border of a disk at regular intervals. Print the result without any infill or top/bottom layers to produce a flexible band. The default pattern shown in the sample image is a simple cloverleaf. Click Open in Customizer to design your own.

I printed the sample in clear PLA on my Printrbot Simple. 0.3 mm layer height, no top/bottom/infill.
