Gridfinity-Cadova

A Swift library for generating Gridfinity storage system components using Cadova. Gridfinity is a modular storage system designed by Zack Freedman that uses a standardized 42mm × 42mm grid.

This project can be used in two ways:

Generate standard Gridfinity parts

Run the included generator to create bins, baseplates, and baseplate sets with configurable dimensions, ready for 3D printing.

Build custom Gridfinity-compatible designs

Import the library into your own Cadova projects and use the provided components as building blocks to create specialized storage solutions that integrate with the Gridfinity ecosystem.

Features

Bins

Bin creates hollow storage containers with configurable dimensions:

Bin(
    size: Units3D(x: 2, y: 2, z: 3),
    wallThickness: 1.0,
    bottomThickness: 0.6,
    innerBottomCornerRadius: 1.0,
    withStackingLip: true
)

• Size specified in grid units (42mm × 42mm × 7mm)
• Configurable wall and bottom thickness
• Optional stacking lip for nesting bins without a baseplate

Baseplates

Baseplate creates the base platform that bins snap into:

Baseplate(size: Units2D(x: 4, y: 4), options: [.tabs, .screws])

Options:

• .foundation – Adds a 7mm foundation layer
• .tabs – Interlocking tabs for connecting adjacent baseplates
• .screws – M3 screw holes and nut traps for secure fastening
• .magnets – 6.5mm magnet slots in each grid cell

Baseplate Sets

BaseplateSet automatically partitions a large area into printable baseplate pieces:

BaseplateSet(
    footprint: Vector2D(713, 495),  // Target area (e.g., drawer interior)
    printbedSize: Vector2D(340, 320),  // Your printer's bed size
    frontPadding: 10,  // Optional non-grid space at front
    options: [.tabs, .screws]
)

Generates:

• Main baseplate pieces that tile the grid-aligned area
• Narrow/shallow pieces for partial grid coverage
• Corner pieces where needed
• Side spacers to fill non-grid gaps on left/right edges
• Front/back spacers for non-grid depth, automatically split to fit the print bed

Blocks

Block creates solid Gridfinity base units (used internally by Bin):

Block(size: Units2D(x: 3, y: 2), height: 42)
