Inspired by some beautiful mechanical iris designs like this one by Chris Schaie I wanted to try if I could design one myself. The iris is an adjustable opening (aperture), which controls the amount of light coming through the lens (i.e. Alter dimensions and refine elements of your iris mechanism on the fly. Set the leaves aside so they can safely dry and harden without being disturbed. Thank you. A 3D program is not a sketch book, make sure you have a plan before getting into it. This is supposed to be a 3D instructable. And you can see lots of variations on the market. Star Wars showed up a lot here (the sliding doors in the Death Star, the top hatch on the Millennium Falcon), and when I saw a drawing posted with curved panels that meet in the middle, this project was born. Provided by the Springer Nature SharedIt content-sharing initiative, Over 10 million scientific documents at your fingertips, Not logged in There are several ways to design and construct an iris mechanism. third layer (for holding all layers together). So I've always wanted to build a mechanical iris, and this 3D design contest sounds like the perfect way to work the bugs out. Not as simple as this design, however. Now that you have the pins glued, it's time to put the whole mechanism together. If you'd like to have a go at making your own iris design, please do sign up to our design software. the "exposure"). Maker-written books designed to inform and delight! Then, carefully position the top ring (the ring with oblong holes) on top, so that the pins from the bottom ring comfortably rest between the holes in the top ring. Once you have your template piece made, you can close the 3D program and copy and paste the file however many times you need it. An important element of the lowfriction aspect of the design is maximization of the flatness of, and provision of small gaps between, adjacent iris blades. http://www.thingiverse.com/thing:2704046.
