Decorative Disks

Here are some decorated disks for a two color printer. The disks print in a few minutes and the openSCAD program provided can be modified to quickly try out ideas for two color prints. The patterns extend completely through the disks which are only 2.5 mm thick. The disks might serve as refrigerator magnets, math teaching tools, earings, or mobiles.

Twelve of the images are derived from plane curves. They are:

cardioid
catenary
evolute of ellipse
sine
three-leaved rose
strophoid
witch of agnesi
lemniscate of bernoulli
limacon
parabola
cubical parabola
semicubical parabola

You will find much information about all of these curves on the internet.

Pairs of stl files for 3 of the disks are included below:
