I have designed several boxes to store different types of cards that my daughter has. These boxes use 6mm (diameter) x 2mm (height) to hold together. The inner dimensions (length x width x height) are as follows:

• card_box_90x64x17mm_6x2magnet.stl: 90mm x 64mm x 17mm
• card_box_90x64x30mm_6x2magnet.stl: 90mm x 64mm x 30mm
• card_box_80x58x54mm_6x2magnet.stl: 80mm x 58mm x 54mm
• card_box_120x82x17mm_6x2magnet.stl: 120mm x 82mm x 17mm
• card_box_134x80x22mm_6x2magnet.stl: 134mm x 80mm x 22mm
• card_box_dual_80x54x54mm_6x2magnet.stl: Dual slots 80mm x 54mm x 54mm
