classic Iris diaphragm

classic Iris diaphragm 3D print model


This is a classic Iris diaphragm. I have designed it with minimal thickness while ensuring strength. It is specifically made for FDM printers and PLA materials. It is crucial to produce it with high quality for the mechanism to function correctly. Please note that the scale should not be changed as it would result in malfunction. If you require a different scale, kindly inform me so that I can customize the measurements according to your equipment and dimensions.

Although the diaphragm can fully close, it requires a slight modification as the current model cannot close completely.

The model consists of 10 blades and 10 pins. After printing, you need to attach the pins to the blades using adhesive. I designed it this way to enable printing without the need for support structures and to expedite the printing process.

The gap between the movable parts is 0.2 mm, while the gap between the pin and the blade hole is 0.05 mm.

I created this model using SolidWorks 2021. Please let me know if you require the original file.

Please note that the assembly file may not accurately depict the actual bending of the blades during movement. It is challenging to simulate blade bending accurately in software. However, I have positioned them correctly, and the virtual assembly functions appropriately. The apparent position of the blades might not appear accurate.
