This is an easy to use playing card older. You need a rubber band to connect part one to part 2 and to secure the cards between them like shown on the pictures. Now you can slide the cards easily between the two parts. The card holder is for the cards on your hand or to lay them down without floating away. print settings part 2                                         part 1, card holder layer hight:            0,2mm                                                   0,2mm first layer:              0,3mm                                                   0,3mm print speed:          55mm/s                                                55mm/s infill:                         25%                                                         25% Brimm 4mm                                       Raft 4mm; 4 layers bottom/top:         1,2mm                                                  1,2mm overhang angel: 45°                                                          45° Material:                ABS                                                        PLA temprature:         240°C                                                    180°C bed:                          110°C                                                     60°C,
