Fabric (With no supports!)
While this fabric works well, I designed another version that looks better and flexes easier. Check it out here: https://www.thingiverse.com/thing:6894982.
This is a simple fabric idea for 3D printing. It shouldn't need supports on most printers because there are no overhangs at an angle higher than 45°. Should be able to move smoothly as soon as it comes off the buildplate. On the files labeled "small", the pieces are half size so that the bottom plate is 0.5 mm thick and 6 mm wide/long and the bars are 1 mm in diameter. The other files have a 12 * 12 mm wide/long and 1 mm thick bottom plate and 2 mm thick bars. In the small files the pieces are 7.5 mm apart and in the big files the pieces are 15 mm apart.
