Parametric Rounded D6

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 th
