A6 DnD Storage Box & Dice Tray – Notebook, Dice & Mini Organizer

I needed a clean and sturdy way to store all my DnD materials for a campaign where I’m currently playing as a PC. Since I use A6 notebooks, nothing on the market really fit — so I designed my own. This box is not only a storage solution, but also functions as a full-size dice tray, allowing you to roll directly inside either half.

✨ Features

• Minimalist, compact design — fits neatly on most shelves • A3-sized interior — perfect for A6 notebooks, handouts, documents, etc. • Doubles as a dice tray — both halves offer stable rolling surfaces • Integrated insert slots — holds: • Plenty of dice (yep… Fireball-level storage) • One character miniature • Several pencils or pens

• Magnetic closure — keeps the box securely sealed during transport

🧱 Printing & Assembly Instructions

1. Print the Trays

Print 2× dnd-dice-tray. Pause at 26.00 mm, insert the magnets (4 for each piece), then resume the print. This embeds the magnets cleanly and ensures perfect alignment.

2. Cut and Install the Mats

Print 1× dnd-dice-tray-frame. Use it as a template to cut your mats (you’ll need 2×). Place the first mat in the bottom tray and lock it using the frame.

3. Add the Slot Layer

Print 1× dnd-dice-tray-slots. Place the second mat and lock it with the slot layer.

4. Final Assembly and usage

Rotate one of the trays by 180°. Close the box — the magnets will snap it securely shut.
