We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Ben Fixed axially is a problem because as the balloon expands it gets shorter and the axial constraint is preventing that from happening.
Use two remote displacements, Behavior = Deformable. You don't show the axial coordinate direction, but assume it is Z.
One remote displacement is scoped to the edge at one end and sets X, Y, Z and Rot Z to 0 leaving the other two free.
The other remote displacement is scoped to the edge at the other end and sets X and Y to 0 leaving the other four free.
