Gridfinity Baseplate Stack Generator

An OpenSCAD-based parametric generator for creating stackable Gridfinity baseplates. This tool allows you to programmatically generate multi-layer stacked baseplates by importing and arranging existing STL models from the Gridfinity ecosystem.

What is This Project?

This generator creates stackable Gridfinity baseplates by alternating the orientation of each layer (flipping every other plate 180°). This approach enables you to print multiple baseplates in a single print job, saving time and material while maintaining compatibility with the Gridfinity system.

The tool supports various Gridfinity baseplate styles and sizes, allowing you to customize:

• Grid dimensions (1x1 to 5x5)
• Number of stacked plates
• Baseplate type (ultralight, normal with clipping connectors, etc.)
• Layer height compensation for perfect interlocking

How to Use

Prerequisites

• OpenSCAD installed on your system (nightly with multithreading enabled is recommended as it speeds the rendering a lot, more info here)

Basic Usage

1. Open the file: Load stackableGrid.scad in OpenSCAD

2. Configure your stack: Modify the parameters in the Customizer panel (or directly in the file):

   // Choose baseplate type
   type = "ultralight"; // Options: ultralight, normal_clipping, normal, normal_magnets, heavy_magnets
   
   // Set the correct height for your chosen type
   plate_height = 4.25; // Match the height to your chosen type
   
   // Number of plates to stack
   stack_number = 2;
   
   // Grid dimensions
   size_x = 2; // [1:5]
   size_y = 2; // [1:5]
   
   // Your printer's layer height
   layer_height = 0.20;

3. Render: Press F6 to render the complete stack

4. Export: Export the result as STL (File → Export → Export as STL)

Available Types

Currently, the following baseplate types are included:

• ultralight: Extremely lightweight baseplate design optimized for material efficiency

  • Available sizes: 1x1 through 5x5
  • Created by @DougKremer_1140077

• normal_clipping: Standard baseplate with snap connectors for secure attachment

  • Available sizes: 2x2
  • Created by @Neel_18926

Note: Additional types (normal, normal_magnets, heavy_magnets) are listed in the code but require corresponding STL files in the source/ directory.

Print Settings

• Ironing: Enable ironing for all top surfaces (increase the speed—it doesn't need to be perfect, just smooth enough)
• Adhesion: Enable Mouse Ears or brim for large plates to ensure corner stability, especially with higher stack numbers
• Layer Height: Set the layer_height parameter to match your printer settings for proper interlocking between plates
