How to make Rotate Dial with rivet?
It looks like "wheel" and "dial" (or "game dial") are other names for this.

I found a couple BGG threads with some suggestions:

How do you make a game dial?
Plastic grommets for cardboard wheels (ala BSG)

The main things you could search for are:


(paper) binding screws/screw posts/chicago screws (there's a site called Chicago Screws that sells them, but it's also a generic name)
paper rivets
brads/brass fasteners


I know you said it you couldn't find small enough rivets, but I searched a bit and it looks like paper rivets are made down to a few mm across,
