3 card badge holder

Most of the three card badge cases i have seen haven't really met my needs for work. This design allows for front and back cards and a slot in the middle to house a third card. one of the sides is designed to allow for a 2mm thick RFID type badge, the other side and the slot fit standard .75mm thick cards. feel free to give me feedback and/or remix your own! Found that printing on the long side with supports gets best results.
