Easy/Cheap Focus Adapter Tutorial

[Alexizupinhea]

This is nice, but I would only use it with a "blank" tip you sometimes get in a 5-in-1 or 6-in-1 laser. It seems like a waste of those very nice diffraction gratings and their twist mechanism. These little things make me enjoy lasers so much more than just a dot.

Yeah definitely, the blanks are useless. Good suggestion.
