Iris Mechanism Blades for 3d Printing - Blender Stack Exchange Autodesk Fusion 360 - Designing an Iris mechanism - YouTube Mechanical irises are very intricately designed mechanisms that are mesmerizing to see in action and if you have a laser cutter, you could make one in less than . Stiffness-based approach has been used to design the compliant version of mechanical iris. A rugged iris mechanism has been designed to satisfy several special requirements, including a wide aperture in the open position, full obscuration in the closed position, ability to function in a cryogenic or other harsh environment, and minimization of friction through minimization of the number of components. After laser cutting the file, you should have two piles of small acrylic circles: one pile should have circles with a diameter of 0.25 inches, and the other with a diameter of 0.4 inches. Now that I know how to use it, I would probably buy a copy. I'm not impressed with my construction skills (now you know why I changed the design from v2 to V3), but it mostly works.

Reply Now we need to top off 5 of the pins connected to the bottom ring to prevent all of the pieces from coming apart. The 5 holes that are closer to the inside of the ring should have 1 acrylic circle glued on top. Inspired by some beautiful mechanical iris designs like this one by Chris Schaie I wanted to try if I could design one myself. A mechanical iris consists of multiple movable blades which open up a central circle when an outer ring is turned. The upper and lower rings are co-centered and are kept in sliding contact. I was not sure how well the press-fitted design would work and was a bit afraid that the parts might be too loose or too tight but everything holds together just fine.
