# 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.
