Red Dragon Inn Card Separator

A friend handed me some kind of thick cardboard promo card that I guess was part of a Red Dragon Inn boardgame expansion, and wanted a 3D print of something with the same size/thickness to help separate his box of cards for the game. So I used calipers and Tinkercad to make this. Tried to round the corners to match standard card size corners and they matched up to the reference card he provided. Figure it could be of some vague use for reference purposes, or at least get me used to the upload system here.
