A subtle artefact of stacking leaves in an array is the issue of pseudo-shortening. Being on the continuing quest to make the perfect iris design, it’s certainly a factor to consider when creating an iris diaphragm. So what do I mean when I use the term pseudo-shortening? Let’s start, like all great iris designs, by […]
Designing an iris to be easily manufactured is obviously advantageous. One particular challenge is making the leaves with pins on opposite sides, and is a common limitation associated with 3D printing on a FDM printer (also known as FFF). This is because parts generally benefit from being printed flat (see my previous article). With these […]
Projection welding is a form of spot-welding, whereby a protrusion of material from one metal part is melted into another, forming a solid bond. This is a particularly useful technique when you have mismatched material thicknesses – such as a solid pin being welded onto very thin leaf material. To make this work for us, […]
This is a guide on how we currently cut the slot for the irises handle in our steampunk goggles. If you’ve bought the Steampunk iris from our store, you may find it useful to follow, or modify, these instructions to cut the slot in your own goggles. For those of you that have a 3D printer, we’ve included a template for you to download and 3D print to help aid the process.
Once you’ve designed and downloaded your mechanical iris as a DXF, what happens next?
Because the Iris Calculator makes no assumptions as to how you might want to fabricate your iris, those DXF files need to be shaped into your final design. In this brief video I show you an example of how you might extrude the housing into a 3D model using SolidWorks.
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.

Opening the aperture reveals your message.

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…
No matter who you are, no matter where you’ve been, there’s always some (good) distractions from the usual work. This time around it was creating a small toy, to go in loot bags for a PJ Masks themed party… Because sometimes even the smallest client is the most important!
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.
