Essential Gridfinity Base Components
Every Gridfinity setup starts with base plates and versatile bin options. The community has moved beyond simple open bins toward more sophisticated base components that save filament and add functionality.
Gridfinity Collection Solid Bins for Customization (STEP Files)
This collection gives you a solid foundation for any Gridfinity layout. The models range from 1×1 up to 5×5 grid units across 9 different heights, so you can mix and match sizes without committing to a specific use case upfront. The included STEP files let you modify the base geometry in any CAD tool for custom cutouts, dividers, or labeling tabs.
Print settings: 0.2mm layer height, 15% gyroid infill, no supports needed. Stick to PLA for office desk use or PETG if the bins go in a garage workshop where temperatures climb. The 3MF files embed a Bambu Lab A1 profile, but the STL exports work in any slicer.

📊 Gridfinity by the Numbers
The Gridfinity ecosystem now includes thousands of community-designed modules across Printables, MakerWorld, Thingiverse, and DIY3D. Zack Freedman released the original specification in 2022 under the MIT license, and the system has since become what the Snapmaker blog calls “the undisputed standard for horizontal organization” in the 3D printing community. A single 2×4 base plate uses 80 to 120 grams of filament, and a fully populated desk drawer can consume 350 to 500 grams before adding any bins. Low-profile base plates (4.75mm vs. the standard 7mm) are now available for shallow drawers, reducing filament use by roughly 30%.
Baseline print parameters:
- Layer height: 0.2mm for most bins. Use 0.16mm or 0.12mm for bins with fine text or small holes.
- Infill: 15% gyroid or honeycomb for bins. 20% for structural parts like drawer bodies and latches.
- Filament: PLA for desk and office use (bed temperature 60℃). PETG for garage, workshop, or any environment above 50℃ ambient.
- Supports: Most Gridfinity bins print support-free. The exceptions are latch housings and overhanging features in drawer systems.
- Bed adhesion: Brim recommended for bins taller than 4 grid units. A brim also helps prevent warping on larger base plates.
- Nozzle: 0.4mm standard. A 0.6mm nozzle works well for reinforced utility bins and reduces print time by roughly 30%.
- Magnet holes: Pause at layer height before holes close to insert 6x2mm or 6x3mm neodymium magnets. Apply a drop of CA glue for permanent retention.
Calibration tip: Always print a single test bin before committing to a full drawer. Gridfinity tolerances are designed for a 0.2mm clearance between bins and base plates, but every printer handles corners and elephant foot differently. One test print saves you a 12-hour reprint.

Common Questions About Gridfinity 3D Prints
What is the Gridfinity system for 3D printing?
The Gridfinity system is an open-source modular storage standard that uses a 42x42mm grid of interlocking base plates and customizable bins. It was created by Zack Freedman in 2022 and has become the most widely used 3D printed organization system for drawers and desktops. The MIT license means anyone can remix, modify, or sell Gridfinity designs without restrictions.
What filament is best for printing Gridfinity bins?
PLA is the best choice for Gridfinity bins in desk and office environments because it prints easily and holds dimensional accuracy well. PETG is preferred for workshop or garage use where temperatures exceed 50℃ because it resists softening and creep. ASA is a suitable option for automotive or outdoor use but requires an enclosure for consistent results.
Do you need magnets for Gridfinity base plates?
No, magnets are entirely optional. Standard Gridfinity base plates use a friction fit to hold bins in place, which works fine for stationary drawers. Magnets add retention for portable toolboxes or vertically mounted setups. Models like the Click-Lock Stackable Lid use mechanical snap fits instead, eliminating the need for magnets altogether.
Can you print Gridfinity on any FDM printer?
Yes, Gridfinity models print on any calibrated FDM printer with a build plate at least 150x150mm. The standard 0.4mm nozzle handles the 42mm grid and bin walls easily. Larger base plates may need a brim for bed adhesion, and printers without enclosures should use PLA for best results. Resin printers are not recommended for Gridfinity components due to brittleness and dimensional shrinkage.
How much filament does a full Gridfinity drawer use?
A typical 2×4 Gridfinity base plate uses 80 to 120 grams of filament. Filling a standard desk drawer with a base plate and mixed bins typically requires 350 to 500 grams total. Low-profile base plates (4.75mm tall) reduce filament use by about 30% compared to the original 7mm specification and are recommended for shallow drawers.
Start Organizing With Free Gridfinity 3D Print Models
The 10 models in this roundup cover the full range of what Gridfinity 3D print designs can do: from quick-print tool holders and battery trays to full modular drawer systems and under-desk storage. Every model is available as a free download on DIY3D, with STL files for slicer-agnostic printing and 3MF files with embedded Bambu Lab profiles for one-click slicing.
Start with the Solid Bins for Customization as your base, then add the specialized holders as you identify the gaps in your workspace. One test bin per type is all it takes to dial in your printer’s tolerance, and the 0.2mm clearance standard means most models will fit together without post-processing.
Gridfinity’s strength is that it grows with your needs. A single base plate with three bins today can expand into a full drawer system next month, and every new module clicks into the same 42mm grid without requiring a redesign.
