Hey Feign
The Graphite worked really well, I didnt have any tap nearly small enough to thread a .3- .5 mm hole, so i just machined a tapered hole that is 1cm deep.

so currently my best setup is some thing like this laser diode-- 3mm-- first aperture--Lens--- 100mm---1cm thick taperd Graphite aperture---->

Id like to get that 100 mm down alot but the light needs space to scatter,
and I think that my first aperture being right up against the lens is probably bad, im going to try giving it a .5 mm gap, and making the first aperture out of graphite too.

any other suggestions, Ill probably try printing with the best thing iv come up with late tomorrow.
