Hex Tile Card Holder

Pirate3D Design Competition An interlocking hexagonal tile card-holder. Each individual tile is 1 inch from corner to corner, so will most likely not be size compatible with standard tile sizes, but my intention is for these to be independent from the usual tile system, with the interlocking ability purely because I like that sort of thing and it looks nice. The design should be able to accommodate a wide range of card sizes and as shown by the photos multiple cards can be fitted. Print time at 15% infill with 0.15mm layer thickness and in PLA is approx. 40 minutes. Measurements are : 8.769 x 4.41 x 1.323 cm
