About this 3D model

All plants love spring. Particularly this spring. Prints without supports. The overhang angle on this spring is pretty steep, but with good cooling and proper settings, it is doable. I printed this in PLA, 0.2mm layers, 2 perimeters, 0.6mm line width, 0% infill. It is nominally 100mm in diameter and 165mm tall. If you are having trouble with the overhang, you can rescale to change the aspect ratio to make it taller relative to the diameter. Either just scale up the Z axis dimension or shrink the X and Y scale and leave the Z scale alone. (Just make sure the Z scale > X-Y scale.)
