The file 'Little Spring 3D Printer Model' is (stl) file type, size is 87.8KB.
I doubled the length (and the number of coils) of the Springamathing 1.0 (http://www.thingiverse.com/thing:12053).
Now you can print it scaled down by about 50 percent to get a smaller and more flexible version of the original spring.
At the picture you can see the long (9in) version of the original spring for comparison.
