I designed this to be machined out of aluminum.
I printed it out of PLA and did a couple of test prints that way. Not sure how long it would last in PLA though.
It uses a 1/4" spring (http://www.mcmaster.com/nav/enter.asp?partnum=9637K66)
It comes in a set of 5 11" lengths that you have to cut to length but it's a pretty beefy spring.
I'm sure there are some other 1/4" diameter springs that would work.
