Customizable Dice / Geometric Cube

🎲 Parametric Dice / Geometric Cube

This model can be used either as a classic six-sided dice or as a pure geometric cube.
By adjusting just a few parameters, the dice can be generated without edge rounding and without pips, making it suitable whenever a simple, clean cube is required.

The model scales reliably while preserving correct proportions, balanced geometry, and a standard dice layout when pips are enabled (opposite faces always sum to 7).

✨ Features

Can be used as a dice or a plain geometric cube
Fully scalable size
Optional rounded edges
Optional engraved pips
Standard dice numbering when enabled
Clean, symmetrical design

⚙️ Parameters

dice_size (mm)

Edge length of the cube.

Controls the overall size of the model.

Geometric cube: any value
Dice: any value

corner_radius (mm)

Edge and corner rounding radius.

0 → sharp edges (pure cube)
> 0 → rounded edges

To create a geometric cube:

corner_radius = 0

pip_radius (mm)

Radius of each pip (dot).

Controls the visual size of the engraved dots.

Only relevant when pips are enabled
Has no effect when pips are disabled

pip_depth (mm)

Depth of the engraved pips.

Controls how deeply the dots are engraved into the surface.

Has no effect when pips are disabled

pip_spacing (mm)

Spacing of pip positions from the center of each face.

Controls the visual balance and readability of the dots.

Only relevant when pips are enabled

render_pips (true / false)

Enable or disable the pips entirely.

true → classic dice
false → blank cube

To create a geometric cube:

render_pips = false

center_model (true / false)

Center the model around the origin.

true → model is centered (recommended)
false → model starts in positive coordinates

25	1.50	1.55	0.85	5.2
30	1.80	1.85	1.00	6.2
35	2.10	2.15	1.15	7.2
40	2.40	2.45	1.30	8.2
45	2.70	2.75	1.45	9.2
50	3.00	3.05	1.60	10.2

🔢 Statistics

I did 100 test rolls with a sample 25mm die, and the values were within the statistically expected range without any number occurring noticeably more often than others. It behaves like a store-bought die.

⚙️Printing Settings

I recommend a fill level of at least 50% and an even fill pattern such as rectilinear or grid.
