Rainbow Six Siege - Currency Pack Business Cardholder [Experimental]

I'm experimenting with multi-part objects that interlock with each other and I figured this might be a cool novelty item for Rainbow Six Siege fans. This includes multiple versions with cuts based on the axis.

Please leave a comment if there's an issue with the design...especially the fit of the registration slots if they don't work.

Prototype 1: "Clam Shell" configuration
Internal dimensions: 92mm x 60mm x 140mm (big enough for US and Australian business cards, as well as credit cards)
