A simple, **parametric** six-sided die with softly-rounded edges and

corners. Three ready-to-print variants:

- **Numbers** (Arabic 1-6) — `rounded_dice_numbers.stl`

- **Roman** (I, II, III, IV, V, VI) — `rounded_dice_roman.stl`

- **Letters** (A, B, C, D, E, F) — `rounded_dice_letters.stl`

Opposite faces follow the standard d6 convention (numeric pairs sum to 7).

## Custom face sets

The OpenSCAD source (`rounded_dice.scad`) is included. You can render

your own face-set with any unicode (up to ~3 chars per face):

```bash

openscad -o my_dice.stl \

    -D 'variant="custom"' \

    -D 'custom_faces=["A","B","3","IV","♥","★"]' \

    rounded_dice.scad

```

Tweak `size`, `corner_r`, `engrave_d`, font, char sizes — all

parameters live at the top of the .scad file.

## Print notes

- Recommended: PLA or PETG, 0.2 mm layer, 2-3 walls, 15-20 % infill.

- Orientation: any face down — corners are rounded so it sits stable.

- No supports needed.

- Engravings are 0.9 mm deep — a darker filament shows them well, but

  they're also legible single-color. AMS optional.

- Cube edge defaults to 16 mm.
