I've printed some cardstock pawns to be used in a Pathfinder game and needed something to hold them. The cardstock I used is about .24mm thick, so the gap in these pawn stands I made .25mm. There's really nothing fancy about these, but they worked for my purposes and thought I'd share.
Slightly filleted at the top of the gap to make it easier to insert the cardstock pawn. This made it easy enough to insert the cardstock pawn, but was held quite firmly in place.
Included is a 1", 2" and 3" stand.
Pawn1.stl for the 1"
Pawn2.stl for the 2"
Pawn3.stl for the 3"
