Double Deck Playing Card Box (Rummy, Burraco, Scala 40, Poker)

Welcome to a new functional design by TonnoSupremo. Whether you're a fan of poker, rummy, or casual tabletop games, protecting your cards on the go is essential. This custom box is engineered to comfortably hold two standard 54-card decks. The core of this design is its reliable clip mechanism: it ensures the lid stays firmly locked to prevent accidental openings in your bag, yet it pops open smoothly with a simple thumb gesture. No more scattered cards or worn-out rubber bands—just pure, functional 3D printing engineering.

• Perfect Fit: Custom-tailored to house exactly two complete 54-card decks, as shown in the open display.

• Smart Clip Lock: A carefully calculated latching mechanism that perfectly balances security against accidental drops and ease of manual opening.

• Modular Structural Strength: To maximize layer adhesion and mechanical strength, the top lid isn't printed as a single, easily breakable piece. It is printed in two separate halves that are mechanically bonded using custom pins.

• Thematic Aesthetic: The bottom base features a sleek embossed design showcasing the classic card suits (Hearts, Spades, Diamonds, Clubs).
  

Assembly & Usage

The box is designed for a robust mechanical fit. Follow these step-by-step instructions:

1. Cleanup: Remove any minor blobs, stringing, or elephant's foot from the printed parts.

2. Pin Testing: Before joining the halves together, test-fit the pins in their respective channels on the individual top pieces to ensure the pathways are clear.

3. Joining: Align and join the two halves of the top lid.

4. Main Pin Insertion: While the order doesn't strictly matter, I highly recommend inserting the large bottom pin first.

5. Lateral Fixing: Finally, insert the 4 smaller side pins. They should slide in relatively easily. If they feel tight, use a rubber mallet to gently tap them flush into place.
