Paris Metro Ticket holder

thingiverse

These small compartments are perfect for storing metro tickets of varying values separately, and keeping them organized in a bag without needing to carry a wallet. Print vertically with no additional supports required, hollowed side up (in the same position as shown in the last image, not as the STL preview displays). Once printed, simply cut off the transverse wire near the top end. This wire was added to serve as a support for overhanging parts and can be easily printed without any problems as a bridge, so there's no need to worry about it.
