I really like it. Taking for example a 50/1.4, if I measure the diameter of the aperture, and of the barrel, would you be able to print one on transparent material? I am just asking because many lenses are easy to open and install one? The apodized bokeh even if stopped to f2.8 has a lovely look.

You can easily get overhead transparency material designed for either inkjet or laser printers. The inkjet stuff looks really hazy because it has a rough coating to absorb the ink. The laser material is more transparent, and will not melt when it contacts the binding drum in the laser (don't try using inkjet transparencies in a laser!).

The catch is that sizing it correctly involves determining the widest aperture at which the lens doesn't vignette, which is very lens dependent.

This is a very good idea. I didn't see it mentioned anywhere. Any suggestion at what shape to print assuming laser?
