Thanks for the reply wiwa!
Oops, the max dimension on this case is supposed to be 5.5 inches. Anyhow, as a student, I apparently get to use Autodesk Inventor free of charge and it has it's own stress analysis function (possibly not the same as Finite Element Analysis, but pretty close I'd think) It wants to know what material I'm using for this, but there's no option for PA 2200 or Polyamide :/ what's a plastic that would be a good substitute so that whatever works with that material should almost definitely work with the Strong and Flexible Plastic? The list of Materials has various Polystyrenes, Polycarbonates, Polypropylene, Polyethylene, ABS Plastic, PET plastic, and PVC.
Also, what do I want to look out for with this Stress testing? What are the indicators of when the cantilever will fail? Here's a pic of what I've been able to do (stress test1.jpg)
I can see the Von Mises, 1st Principal, and 3rd Principal Stresses as well as the Displacement when I place a load of .1 lb (sensible?) on the end of it.
Lastly, Why is getting the Snap-fit out so much more difficult than getting it in?
Also, I know trial and error is a good thing for this sort of stuff... but I don't wanna xP at least not for $60
