I've built a laser with an M140 diode, and want to install a star cap in place of the G2 lens.

Is there any set of star caps available that can screw into the housing?

Am keen to experiment with making a bat signal type arrangement too. Anyone done this?

How easy is it to make a star cap with your own design?

The caps are actually holograms, so not very easy to make. Unless you mean just to physically block an expanded beam. Then a 3D printer would be your friend, although plastic would probably melt quickly at 2 watts
