Summary

Can it be printed successfully? Sure! Coils touche only at the edge of each level so it's easy to separate them.

Post-Printing

Using the back of a box cutter to separate coils is recommended.

How I Designed This

It's actually inspired by Customizable Slinky. I put a helix_extrude module in my library. This thing is an example of application. The code is easy if you use the module.

include <circle_path.scad>;include <helix.scad>;include <rotate_p.scad>;include <cross_sections.scad>;include <polysections.scad>;include <helix_extrude.scad>;spring_radius = 25;spring_levels = 30;spring_sides = 48;line_thickness = 2.5; module toy_spring(radius, levels, sides, line_thickness) {    $fn = 4;    shape_pts = concat(        circle_path(radius = line_thickness / 2)    );    helix_extrude(shape_pts,         radius = radius,         levels = levels,         level_dist = line_thickness,        $fn = sides    );}toy_spring(    spring_radius,     spring_levels,     spring_sides,     line_thickness);
