In my project the exported glTF file does not preserve the modifier properties set to spirals when the animation runs, causing these spirals to float independently without any attachment to the armature rig. These spirals are however working correctly when the rig is played around with in Pose Mode. I'm a novice when it comes to Blender but I figured it has to do with the animation settings.
(I tried baking the animation, but that removed the springs altogether)
