Spirograph

For kids from 7 to 77 years old! Here is a tool to draw beautiful geometric figures.

All elements are printable on a 15x15 cm tray

To draw:


Place a base on a sheet of paper, notches below.
Place a wheel in the center empty area, with its notches touching the notches on the base.
Place the tip of a pen or marker in one of the holes in the wheel: the hole closest to the edge will give an ample figure.
Spin the wheel, keeping the pen square to the paper.


Here is a link to a site with a great spirograph application:

Parameters to set in this app:


Set the stator to 96
Use only one rotor by deleting unnecessary rotors with "X Delete last rotor". Check its option h (rotor inside)
Set the rotor to the number marked on each of my wheels
In Pen, the r value corresponds to the location on the rotor radius (corresponds to a selected hole on my own wheel), w to a line thickness, c to a pen color.


All my photo examples were created on this site.
