Circular gasket customizer

Wanted to make a simple circular gasket with a specified number of holes around it, but with smoothly radiused edges. Took a considerable amount of trigonometry to do.

Can export the rendered file as an SVG, import into InkScape and convert into GCode for a laser cutter, plotter etc.

If the stud holes are not evenly spaced, you can introduce a variable, say, j, where j=[0,45,75,213,310]; (for example). In the "for" loop, you can rewrite:

for(i=j){
rotate(i) ...
}
