Blade for optical chopper (customizable)

This is a custom blade to be used with a optical chopper (In the lab we use a MC2000 from Thorlabs). Type 0 immitates an MC1F10 blade, meaning that the part near the edge of the blade has 10 equally spaced slits, so that the MC2000 has no problem locking the movement of the blade to the required frequency, but the most central part has slits that allow 1.6ms of dark and 0.4ms of light.

"Blade1.scad" is the first design, I updated the design with a larger blade and thinner outter circuference
