Optimally Packed Gridfinity
Print Profile(0)
Description
Standard Gridfinity layouts are usually restricted to orthogonal grids (like 3x3 or 4x4), which often leads to significant wasted space when you only need a specific number of bins (like 5, 11, or 17).
This project breaks that limitation by leveraging mathematical research on "Square Packing in a Square." By using precise geometric translations and rotations, we’ve created high-density baseplates that fit more bins into smaller footprints than traditional grids allow.
Key Features
Space Efficient: Fits "awkward" numbers of bins into the theoretical minimum possible square area.
Fully Compatible: Uses standard 1x1 Gridfinity "islands," so your existing bins will click right into place.
High Quality: Models are rendered with high polygon counts ($fn=64$) for smooth, precise fitment.
Open Source: Parametric OpenSCAD source files included for all layouts.
Available Layouts
Slots | Size (mm) | Improvement over Standard Grid |
|---|---|---|
5 | 113.7 x 113.7 | 44% smaller footprint than a 3x3 grid. |
10 | 155.7 x 155.7 | Fits 10 slots in less space than a standard 4x3 grid. |
11 | 162.8 x 162.8 | Highly compact "rigid" packing. |
17 | 196.4 x 196.4 | Fits 17 slots in less space than a standard 5x4 grid. |
19 | 205.2 x 205.2 | Optimized 19-slot layout using 45° rotations. |
26 | 236.1 x 236.1 | Fits 26 slots in a footprint smaller than a standard 6x5 grid. |
Technical Details
These plates are generated using OpenSCAD and the gridfinity-rebuilt library. Each design features a 1mm structural floor connecting the "islands" to maintain rigidity while minimizing filament use.
