Hi,

I am trying to model a 3D printed prototype that I have. 

The part can remain completely flat but also be deployed with the top structure rotating during deployment (as seen in the pics). 

I am having trouble with my assembly file. Does anyone have any suggestions on how to constrain my mates so that the parts don't go through each other or freak out and start twitching? I have also tried setting up axes for the parts to move along, but it's still not giving me the full freedom to just move the top structure up and down. 

Thank you for taking the time to help!
