The spring design requires the filament to be somewhat flexible and elastic. Design files are linked below for anyone who wants to adjust the spring thickness / tolerances. PolyMax isn't quite elastic enough for this spring, but Colorfabb PLA/PHA (which is more flexible than normal PLA) seems to work well. A [new version](http://www.thingiverse.com/thing:983879) is available, this one should works better with the more brittle plastics.
