Holder for Arkham Horror "Chaos Tokens". Prevents the cardboard tokens from sticking together in the bag while being a bit smaller than the coin collectors that many folks use. I added some knurling round the outside because I fiuigured that chaos tokens should have a little "tooth".
Design uses a circlip, which snaps in over the token. After inserting the token, insert the circlip into the slot, starting away from the gap in the clip and press it into place, working toward the gap. If the ends of the gap stick together, don't free them, seems to work well with a little bridge to keep them aligned.
Design is tuned to the 0.15mm layer height (there are some thin walls).
