SortForge is a single-file OpenSCAD parametric tray generator designed for MakerWorld Parametric Model Maker. It creates clean, printable compartment trays with adjustable outside size, row/column layout, preset mixed-bay layouts, labels, scoops, pour spouts, rim styles, and optional Gridfinity-compatible underside feet.

Use it for sorting screws during repair work, keeping electronics components separated, organizing board-game tokens, holding jewelry findings, staging craft supplies, or making custom drawer trays for workshop small parts.

The default model is a 180 x 120 x 24 mm tray with a 3 x 4 uniform grid, rounded corners, front scoops, and raised cell-number labels. The model is intentionally primitive-based and fast enough for PMM use. Cell-number labels use lightweight geometry by default instead of expensive font text.

Gridfinity behavior is optional. In `tray_size_mode="manual"`, the tray length and width stay exactly user-controlled even when the Gridfinity base is enabled. In `tray_size_mode="gridfinity_units"`, the outside size is derived from the selected Gridfinity pitch and unit count.

## Customization Notes

- Choose `layout_preset="uniform"` for regular row/column trays.

- Use `hardware_matrix` for many small screw/electronics cells.

- Use `big_left`, `big_right`, `big_center`, or `two_large_four_small` for mixed-size parts.

- Enable `front_scoop` for easier finger access to front-row compartments.

- Set `label_mode` to `cell_numbers`, `prefix_numbers`, or `custom_title`.

- Use `tray_size_mode="manual"` for exact drawer or bench dimensions.

- Use `tray_size_mode="gridfinity_units"` when the Gridfinity unit count should control outside dimensions.

- If PMM generation feels slow, reduce `preview_quality`, disable labels, or use fewer rows/columns.
