# Wargame Accessory Box & Dice Tray

A parametric OpenSCAD box for carrying tabletop wargaming accessories.
Three printable parts:

| Part     | Purpose                                                            |
|----------|--------------------------------------------------------------------|
| `box`    | Open tray. With the insert removed it doubles as a dice tray.      |
| `lid`    | Fully detachable friction-fit lid (no hinge to get in the way).    |
| `insert` | Removable compartment tray for tokens, measuring tapes, etc.       |

## Quick start

Open `wargame_box.scad` in OpenSCAD and set the three `total_*` values to
the free space in your backpack — they are **outer** dimensions and
`total_z` already includes the closed lid, so the printed result fits the
measured space exactly.

Pick what to render with the `part` variable (or the customizer):
`assembly` (exploded preview), `box`, `lid`, `insert`, `print`.

Or export everything from the command line:

```sh
make            # exports stl/box.stl, stl/lid.stl, stl/insert.stl
```

## Configuring the insert layout

Compartments are defined by the `layout` list, one entry per row
(front to back):

```
layout = [
    [1.0, [1, 1, 1, 1]],   // front row: 4 equal token bins
    [1.0, [2, 1, 1]],      // middle row: 1 double-width + 2 small
    [0.8, [1]]             // back row: full-width slot (tapes etc.)
];
```

* The first number is the **row depth weight**.
* The list is the **column width weights** within that row.

Weights are relative, so the layout always fills the insert exactly no
matter what box size you choose. A row weight of `2` is twice as deep as
a row of weight `1`; a column weight of `2` is twice as wide as `1`.

To print a second insert variant (e.g. for a different game system), just
change `layout`, re-export, and swap inserts as needed. Two half-height
stacked inserts are possible too: set `insert_h_override` to about half
of the automatic height and print two with different layouts.

## How the parts work together

* The **lid** is a flat plate with a lip that plugs into the box opening.
  `lid_clearance` (default 0.2 mm per side) controls the friction fit —
  print a test fit and adjust for your printer/material. Shallow thumb
  grooves on the box's front and back walls let you pry the lid off; they
  do **not** pierce the wall, so the dice tray stays fully closed.
* The **insert** sits below the lid's lip, so the lip also keeps loose
  tokens from jumping compartments in the bag. Finger notches on its
  short walls let you lift it straight out; then the empty box is your
  dice tray. `tray_chamfer` puts a 45° bevel around the floor edges so
  dice don't lodge in the corners.

## Printing notes

* No supports needed for any part. Print all parts flat side down
  (the lid prints plate-down, lip up).
* PLA or PETG, 2–3 perimeters, ~10 % infill (the parts are mostly walls).
* If the lid is too tight/loose, tune `lid_clearance` in steps of 0.05 mm.
  Same for the insert with `insert_clearance` (looser is fine there —
  it just needs to drop in and lift out easily).
* A piece of felt glued into the box floor makes dice rolling quieter;
  if you plan this, add the felt thickness to nothing — the inner depth
  is generous — but you may want `tray_chamfer = 0` for a flat floor.
