* Pololu's stencils: "Our stencils are made from 3-mil or 4-mil mylar with a low-power CO2 laser. The finest pitch we can handle is approximately 0.5 mm, and we strongly recommend that fine-pitch stencils be cut from the 3-mil mylar."
* Use raster instead of vector processing of gcode. Using raster will cut/burn
away the whole section, instead of leaving dangling rectangles. This would
entail using `raster2gcode` instead of the J-Tech Inkscape plugin.
* Use 2-4 mil Kapton film instead of mylar. Sample: McMaster P/N 2271K2.
* Use paper instead of mylar.
* "The secret to cutting mylar stencils is to stack two 7mil sheets together and cut them at the same time! Unlike Kapton stencils, the Mylar will melt if exposed to large amounts of heat." juanjchong.com
* Use finer focus lens on LASER.
