Hello Maddie
I know I'm a bit late, but, I can and am cutting masks for telescopes.
I have cut Bahtinov, Tribahtinoc and Duncan masks for members ( and others ) on IIS - I am using either 1.5 or 2mm black plastic sheet.
If you have a sketch or a drawing I can quote it for you, generally delivery ( sending from here in Bathurst ) is about 24 -36 hours.
If interested PM or email me
