Here’s a short video demonstrating 5 steps to making Steampunk goggles mechanical iris diaphragm. Once you’ve 3D printed the parts it’s relatively straight forward to put together.
8×10″ card, incorporating a 5 blade iris mechanism with a 3.5″ aperture, made of reflective card stock.
Opening the aperture reveals your message.
Message can be easily replaced, and the card used again.
3D printers are incredible pieces of tech. With the lowering the costs of FDM (Fused Deposition Modelling) printers in recent years, it has enabled desktop fabrication to reach the masses – both in the small business environment, and in the home. Sometimes, however, printing a seemingly simple object can also prove to be equally impossible. Including a way to 3d print leaves for an iris diaphragm…
This week, I set myself the challenge of creating an iris that was simple and easy to make. A paper mechanical iris that required no additional materials, or construction techniques, accessible to all. Could it be done?
I decided to do something today that I have been wanting to do for a long time; which is to stencil an image on the blades of an iris. This, I figured, has no real practical use – perhaps a new Iris Calculator business card – but none-the-less it would be an interesting effect to see. And as it’s Canada day today, what better image to use than the Canadian flag!
Manufacturing mechanical an iris diaphragm blade, identically, multiple times is a challenge. Usually you’re dealing with very thin material and needing to mount pins securely, with a high degree of accuracy. Here is a somewhat subjective run through of various methods of making blades for your iris.
Building an iris diaphragm needn’t always require specialist tools and materials. A perfectly functional aperture can be easily created from craft materials found around the home. All it takes is a little patience and a steady hand.
