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.
In the video I import the housing dxf file, then proceed to extrude the slots, base, and outer wall. I then create a groove on the inside of the outer wall, for a retaining clip to sit in (which will hold the actuator ring in place). Next I cut a slot for the handle – remembering to make allowances for the width of this handle. Then, finally, I chamfer the edges of the slots (to aid insertion), the edges of the max aperture (to help prevent the blades snagging when the aperture is operated), and the retaining clip groove (again to aid insertion).
