You can print the stem, inner, cap and spring without rafts or supports. Please note that the figure is upside down so that the required negative space is clean after the print.
The plastic spring doesn't work very well I'm afraid and is mostly just for show. It will quickly deteriorate with use. If you want this thing to work flawlessly like a real PEZ dispnser, I suggest pulling the metal spring out of a real PEZ dispenser instead.
After printing, place the cap and spring into the inner part then snap the inner part into the figure. Once this is done you can slide the inner part into the stem.. It's hard to explain how it all snaps together. I suggest buying a PEZ dispenser in the store and gently prying it apart with a small screwdriver to see how it goes together.

I got the 3D model of Bill Clinton from the national archives, so I think it's public domain. I used TinkerCAD to add the negative space to the bottom.
I got the negative space from:
Thanks tbuser for that.
The rest of the parts I got from:
Thanks Jack Imakr for that however, when compared to a real dispenser, these models are slightly too big causing various issues. The ones provided in this project have been corrected so they should work a lot better.
The plastic spring I made from scratch using TinkerCAD.
