Re: Printing

Do you know if there's any name for a tool to cut perfect circles? I guess I will start apreciating lens centering after this experiments.

I may be missing something, but I don't think you have to center apodization masks to optical precision. Just make the clear aperture undersized according to your ability to center it.

Also, print the outer circle too, so you know where to cut.
