The Mag-Vault: Premium Magnetic Deck Box

Official Documentation & Assembly Guide

Welcome to the Mag-Vault ecosystem! The Mag-Vault is a fully parametric, zero-support, magnetic deck box designed for Trading Card Games (Magic: The Gathering, Pokémon, Flesh and Blood, etc.). This document covers the printing, assembly, and customization of the V1 core system.

1. System Overview

The V1 ecosystem consists of two primary modules:

1. The Mag-Vault (Deck Box): Features a mechanical 4-point ball detent snap-fit lock on the long edges and a card-funnel lid to prevent sleeve snagging.

2. The Mag-Connect (Accessory Drawer): A modular sliding tray for dice, counters, and tokens that magnetically docks to the back of the Mag-Vault.

Key V1 Specs:

• Support-free design: All components are optimized for flat-bed FDM printing.

• Hardware: Utilizes standard 10x2mm neodymium magnets.

• Sizes: Pre-configured STL files are provided for 40, 60, and 100-card capacities (Single and Double-Sleeved).

2. Bill of Materials (BOM)

To fully assemble one Mag-Vault with a docked Mag-Connect drawer, you will need:

• 3D Printed Parts:

  • 1x Deck Box Bottom

  • 1x Deck Box Lid

  • 1x Drawer Shell

  • 1x Drawer Tray

• Magnets: 12x Neodymium Magnets (10mm diameter x 2mm thickness or other you want to use)

• Adhesive: Super Glue (Cyanoacrylate / CA Glue)

3. Printing Guidelines

The models have been engineered with tight tolerances for a premium feel. For the best results, adhere to the following slicer settings:

• Material: PETG is highly recommended for the main box. Its natural flexibility enhances the "snap-fit" mechanical locks and increases durability. PLA works well but the locks may feel stiffer.

• Layer Height: 0.20 mm (Do not use thicker layers, as it will negatively impact the sliding mechanisms and ball detents).

• Perimeters/Walls: Minimum of 3 walls for structural rigidity.

• Infill: 15% - 20% (Gyroid or Hatched Cross).

• Supports: NONE. Ensure all parts are placed flat on the build plate. The teardrop-shaped magnet holes are designed to print perfectly without support structures.

4. Assembly Instructions

Step 1: Establish a Polarity Standard (CRITICAL)

Before gluing anything, decide on a universal magnetic polarity for your ecosystem. Establishing this standard early is vital, as the Mag-Vault is a continuously expanding ecosystem. Future expansions (such as daisy-chaining double-sided drawers, Commander display panels, and other upcoming V2 modules) will heavily rely on this uniform polarity to seamlessly snap together in any combination.

• Pro Tip: Stack all your magnets in one tall pillar. Use a permanent marker to draw a dot on the top magnet. This marked side will be your universal "Outward" facing side for the deck box, and the unmarked side will be "Outward" for the drawer.

Step 2: The Deck Box (4 Magnets)

1. Locate the 4 magnet sockets on the back of the assembled Deck Box (2 on the bottom half, 2 on the lid).

2. Apply a tiny drop of CA glue into the sockets.

3. Press 4 magnets firmly into the holes. Ensure they sit flush with or slightly below the plastic surface.

Step 3: The Mag-Connect Drawer Shell (4 Magnets)

1. Locate the 4 sockets on the front face of the Drawer Shell.

2. Check polarity! These must attract the magnets on the Deck Box.

3. Glue and press the magnets into place.

Step 4: The Sliding Tray (4 Magnets)

1. Locate the 4 sockets on the back of the sliding Drawer Tray.

2. Check polarity! These must attract the magnets located inside the Drawer Shell.

3. Glue and press the magnets in.

Step 5: Curing

Important: Leave the parts separated in a well-ventilated area for at least 2-3 hours. CA glue releases fumes as it cures, which can leave a permanent white residue (blooming) on the plastic if the box is closed too early.

5. Customization (OpenSCAD Guide)

If the provided STL files do not fit your specific needs, you can generate a custom Mag-Vault using the included .scad source file and OpenSCAD (a free software).

1. Download and install OpenSCAD.

2. Open the Mag-Vault_V1.scad file.

3. Open the Customizer panel (Window -> Customizer).

4. Adjust the parameters:

   • Card Capacity: Type in any number of cards (e.g., 80, 120).

   • Sleeve Type: Toggle between single or double sleeves.

   • Cut Style: Choose between Sharp (20°), Angled (15°), or Straight (0°).

   • Tolerances: If your printer over-extrudes, increase the printer_clearance setting (default is 0.2mm) to make the lid slide on easier.

5. Select the part you want to render in the Display Mode dropdown.

6. Press F6 to render, then F7 to export as STL.

Happy printing, and may your top-decks be legendary! If you enjoyed this design, please consider leaving a make and a review.

Support My Work

I'm sharing this design for free for the community to enjoy! Designing, testing, and tweaking parametric models takes a lot of time (and a fair amount of filament!). If this deck box keeps your cards safe and you'd like to support my future 3D printing projects, tips are never expected but always deeply appreciated!
