Paris Metro Ticket holder

These little holders are convenient to keep metro tickets of different value separated, and to keep them in a bag without needing a wallet.

Print vertically without additional supports, hollowed side up (in the same position as shown in the last photo, not as the STL preview shows). Once printed, cut off the transversal wire near the top end. It has been added so that it serves as a support for the overhanging parts, and is itself printed without any issue as a bridge, do not worry about it.
