	Using 1mm thick cardstock at a power of 20 Watts and a travel speed of 10mm/sec I was able to produce the following. I assumed the same 0.15mm halfkerf. The results are amazing! The spars and ring are thick and sturdy and they fit perfectly in my filter tray!		Using 1mm thick cardstock at a power of 20 Watts and a travel speed of 10mm/sec I was able to produce the following.

+There is a kerf bug. Technically the kerf is the entire width of a cut, not the difference between expected and actual edge coordinates. The script is actually looking for 1/2 of the kerf. So if your cut is 0.3mm wide then you need to put in 0.15mm as your kerf. Oops. I'll fix that someday.

 ==Problem Statement==
-I want darkfield and oblique with my low and medium magnification objective lenses. I want them to be repeatable in case they break or I find another needy scope. I want them easy to make and use so I can share them with the world. They need to fit in the filter tray. I also don't really know what sizes I need so I want a way to generate a laser cuttable geometry that can sweep a variable over whatever range.
