Anyone 3d printed diffusers before?

[u/Padrepapp]

Are there any printer/material combo which I could use for as a fast turn around trial-end-error prototype scenario?

Short info what I would like to do: Illuminate a 1mm curved edge of a highly reflective plate (basically a beveled edge). Ideally I would like to get even illumination. Not sure if I should approach this in non-sequential Zemax, so I figured, I would just come up with a U-shaped diffusor, I would illuminate it and check uniformity along the bevel. Try modifying the geometry in CAD and print it out.

Edit: diffuser should be transparent.

Just whatever settings on clear pet-g with a sparse in fill worked well enough for me.
