The cup basically works because it is made of flexible Silicon but I want to make it with rigid bodies, what assembly mechanisms could work?
This should get you started. After you finish the sides you can save out the bodies and then build an assembly.
I can model the part file. I can't figure out the mechanism by which it works.
When you create the assembly you can use limit mates for the parts.
so, rigid cylinder bodies (full or partial (arcs)?) ,.. you'd probably need pivoting/side/twist to allow for the inverting... maybe like a collapsing wire egg basket?
