I made the blider a bit shorter so it is more comfortable to use on normal glasses.
The fixed iris has a 3mm diameter. Just enough to make it a bit easier to focus back and forth without acting like a pinhole or obscuring too much light.
All in all ... still less than $2 ... bare in mind that the paperclip does add some cost!
