Ellipsograph
thingiverse
This is my new and improved 3D printed Ellipsograph which makes different sized ellipses. The distance from the pencil to the 1st hole is the semi-minor axis and from the pencil to the 2nd hole is the semi-major axis. The Ellipsograph in action can be seen at http://youtu.be/onm_RKfKY1Q Instructions You will need to print out two sliders. Insert them into the slider chutes and then place the handle over the pegs depending on what size of ellipse you want to draw.
