If someone needs different diameter of a Bahtinov mask made locally (Oz), this is where I ordered it:
Online Laser Cutting
hello@onlinelasercutting.com.au
I asked Lyndsey to use 3mm black acrylic and he has my drawing
<Bahtinov-110mm_vec.pdf> for 110mm OD, which you are free to use ..
2 copies of this cost $25+gst and shipping, roughly $30 and it was done in a couple of days ..
I think you can ask Lyndey to enlarge the diameter to suit your lenses ..
