Other Sizes available: scroll down to see. When I model in 3D it often feels like I'm sculpting. I build each piece, put it into place, tweak/adjust, then add the next piece. With the Triangulated cuff I really wanted a design that seemed minimal yet dynamic, and I adjusted my model until I got the effect I was satisfied with. The final result was 3D printed in a black plastic nylon material (BSF - Black Strong & Flexible). It's a very lightweight yet strong and flexible material (as the name implies). The ends of the cuff are rounded so it slides on and off easily. Sizing: *Size Extra-Small/Petite interior dimensions: 2 1/8 inches wide x 1 1/2 inches tall [54mmx38mm].
