I designed this two part case as I needed something to protect my old and battered playing cards as I carry them pretty much everywhere.
I have added some extra dovetail type joints to help the case slot together smoother, there are also air channels to try to reduce the chance of cards getting stuck however this isn't guaranteed.
I have also included the STEP file for the lid if you want to add your own design to it but I would only recommend you do this if you have a multi-material printer.
