Make: Geometry

a radius of 10mm, and we step up 6mm at a time until we reach at most

60mm (here it would be 58). Here is what the other variables do, shown as

in-line comments. All measurements are in millimeters.

w = 2; //line width of each “D”

h = 3; //the thickness in the vertical direction

hole = 2; //radius of the notch to draw the parabola

point

The variable enclosed set equal to TRUE will draw a whole circle around the

place you will draw the parabola point. Otherwise, it creates a half-circle

notch. If you change its value to TRUE you might need to increase the spacing

(second value in the radii set) to keep them from overlapping.

If you don’t have a 3D ...
