I am new to the Forum and did not see the check mark for a question. Also not sure my reply to a previous post on this topic will be read so I started a new thread. I also am stuck in the Factory Place. I found the putty but have not been able to get out of there. I searched every room available to see if I had gotten all of the objects and have not found any others. Am I missing something? What do I do next? Thanks.

Hard to say if you're missing something, as I don't know what you've done so far ;-)
Here are two walkthroughs, which cover it all. Check them to see if there's anything you might have missed.

This one is brief but sufficient:

Thanks. Very helpful. I am back running again.
