Mechanical Iris mechanism with 5 blades

prusaprinters

<p>Based on some inspiration from the internet I have designed an iris mechanisme with 5 blades. The previous iris mechanism had 3 blades and had a different mechanism. <a href="https://www.printables.com/model/270201-iris-mechanism-based-on-3-blades">https://www.printables.com/model/270201-iris-mechanism-based-on-3-blades</a></p><p>I really like this design and it needs no glue. With the right printer settings it just snaps together. I created 3 different designs for the the teeth. They can be selected as per your style.</p><figure class="media"><oembed url="https://youtu.be/DARlunIxPi8"></oembed></figure><p>Printing instructions:</p><ul><li>Print the teeth model 5x (either variant 1, 2 or 3)</li><li>Print the Ring A, Ring B and Spur Gear each 1x</li></ul><p>I have printed the model on layer height 0.2 mm</p><p>Assembly instructions:</p><ul><li>Put the 5 teeth on ring A in closed position</li><li>Put the spur gear arround so the teeth fit within the gear and the iris is closed</li><li>Put ring B on top of ring A and gently press it closed.</li></ul><p>&nbsp;</p>
