📌 What

Gridfinity-compatible baseplates and bin bases implemented as reusable OpenSCAD modules for anyone to use. This library makes it easy to integrate Gridfinity interfaces into your models.

Baseplate: Use for Gridfinity-compatible shelves or drawers
Bin Base: Use as a foundation for custom Gridfinity bins

🤔 Why

Mainly because I can, but also other implementations I found were pretty complicated and I just wanted simple interfaces.

Standard 42mm Gridfinity grid — compatible with the entire ecosystem
Parametric OpenSCAD modules — include in your own projects
Spec-compliant with grizzie17’s Gridfinity specification

🔧 How

Using the Library

Include Gridfinity modules in your OpenSCAD projects:

include <gridfinity/lib/baseplate.scad>
include <gridfinity/lib/binbase.scad>

// Create a 3×2 baseplate
baseplate(units_x=3, units_y=2);

// Create a 1×2 bin base
binbase(units_x=3, units_y=2);

// Create a bin base with a flat top plate (useful as foundation for custom geometry)
binbase_with_topplate(units_x=2, units_y=2, topplate_thickness=2);

Customizing Parts

Open any file in parts/ with OpenSCAD and use the Customizer panel to adjust parameters:

baseplate.scad: Customize grid dimensions (x and y units)
binbase.scad: Customize grid dimensions and preview with baseplate

Exporting Variants

The flattened/ folder contains pre-configured variants for export as self-contained files to MakerWorld or other platforms.

🧩 Core Components

1. Baseplate

Mounting surface for Gridfinity bins and organizers.

Standard Gridfinity 42mm grid spacing
Precise dimensional compliance with grizzie17’s specification
Optimized for 0.4mm nozzle printing
Compatible with all standard Gridfinity bins

2. Bin Base

Bottom mounting component for custom Gridfinity-compatible containers.

Standard Gridfinity 42mm grid spacing
Matches baseplate cutout geometry
Stack securely on Gridfinity baseplates
binbase_with_topplate() adds a flat plate on top — handy as a foundation for custom geometry
All modules are BOSL2-attachable (anchor, spin, orient)

📐 Dimensional Standards

All dimensions follow grizzie17’s Gridfinity specification for maximum compatibility.
