3D model description
A pantograph is a four bar linkage based on a parallelogram that scales the movement of a point by a set factor.
For the sake of simplicity, the design is non adjustable but I have included linkage files for scale factors (SF) of 2, 3, 4, and Pi.
After putting the design through some tests, I found the margin of error to be consistently under 1%.
