3D Printing Hinges

Hi everyone! Thanks for helping!

So, I am trying to print something with a 'print in place' hinge. It's not a big hinge, but it's also not a small hinge. I find that whenever I am done printing it, it doesn't actually close. There is something that is keeping it open. Any suggestions? I added a images of what sizes I am using for inner/outer diameter of the hinges, what the part looks like etc. I have tried making the hinge dimensions smaller, larger, everything I can think of.  The hinge seems to print fine, but when trying to close it, it does not. You can see what it does in the last image. PLEASE HELP!! Have been trying to solve this forever.

Try reducing your plate thickness.

Move one of the top faces back 0.5 mm.

@brassem explained it well. I would just add that even if you have what he/she calls "perfect alignment" you may still run into issues because of the intrinsic imperfections of FDM 3D printing. Different printers have different tolerances, so I always add in a bit of extra clearance.
