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 is available, this one should works better with the more brittle plastics. Printer: -- Eustathios Design: -- OnShape Filaments: (full list can be found on -- Colorfabb Blue Grey PLA/PHA -- Polymaker PolyMax White (filament donated by PrintedSolid)
