badge holder solid back for 0.8mm PVC film, with lettering on back

I needed a container to hold our monthly public transport ticket.
this tickets here are simply printed on thin paper, so if you share it within the family it should better be protected. I had some 0.8mm thick PVC film wich I cut to size.
so the film slides in front of the ticket.
The cutout letters were filled with 25% hex infill in prusaslicer as postprocessing
