Printing & Scaling Tips

When adjusting the inner diameter, make changes in 20 mm increments if problems occur. (this is due to the complexity of this model. Larger jumps (for example from 50 mm to 200 mm) can overload the parametric engine, resulting in errors or misaligned parts.

Use basic print settings—0.2 mm layer height, 20% infill, supports disabled—for reliable results. If you want extra flair, enable fuzzy skin on the handle for a subtle, tactile finish.

Assembly

Assembly is straightforward with super easy steps

Step 1

Start off by aligning your leaves and inserting screws through the slider

They should all be aligned in the shut position

Step 2

Align the handle with the 5 screws holes. 

Then screw the 5 screws in. 

Now the iris mechanism should work

Step 3

Finally glue/press fit the iris mechanism into the box. (Warning: you will not be able to change it if you glue that’s why I recommend the press fit)
