The Peaucellier linkage transforms a rotary input motion into an exact straight line output motion.
During the Industrial Revolution, mechanisms for transforming rotary motion into linear motion were an area of intense research. Applications for these mechanisms included guiding pistons of the early steam engines and manufacturing precision parts.
The first attempts to solve this problem included Watt's linkage, which only approximates a straight line, and the Sarrus linkage, which does not operate in a single plane.
The Peaucellier linkage generates a perfect straight line by geometrically inverting a circular curve.
Upon seeing a model of this mechanism, Lord Kelvin is reported to have claimed that "it is the most beautiful thing I have ever seen in my life."

Print the following set of parts:
1 x Base Platform
1 x Base Upright
5 x Medium Arms
2 x Long Arms
4 x Long Pins
3 x Short Pins
Assemble as shown in the images using the pins.
If you wish to change the dimensions of the links, the distance between the centers of the uprights must be equal to the distance between the hole centers of the input rotary arm for the linkage to work correctly.
