This tiny Springo is more 'springy' than the larger ones. It has the same tolerances as my larger models so it's a good quick test before printing larger Springos.
Ideally, you should not scale this model and print at .15mm layer height. I carefully split the layers apart using an X-acto knife. They should come apart quite easily without having to cut through plastic, you are simply pulling apart the weak bond between the rings.
If your layers aren't separating, try lowering print temp./increasing print speed. Quick layer cooling helps so use your cooling fan at 100%.
2+ shells, 100% infill.
