Gridfinity Baseplate
This page hands you a gridfinity baseplate in one click: pick a preset — 1 × 1, 2 × 2, 3 × 3 or 4 × 4 — and download that exact plate as its own watertight STL. Every gridfinity baseplate follows the community standard: 42 mm cells, 5 mm thickness, generated locally in your browser with no login and no upload.
Each preset is a distinct model, not one scaled mesh: the 1 × 1 prints 42 × 42 mm for a single desk cell, the 4 × 4 covers 168 × 168 mm of drawer floor, and the size panel confirms the numbers before you print. Choose Custom and the same gridfinity baseplate page reveals X and Y cell fields for sizes in between.
Think of this as the grab-and-print side of the site. When a measured drawer needs a designed plate — cells beyond 4 × 4, bed splitting, a numbered ZIP — the baseplate generator handles that; here, the four standard gridfinity baseplate sizes are one click away.
What is a gridfinity baseplate?
A gridfinity baseplate is the foundation of the system: a 5 mm plate whose cells pitch at exactly 42 mm, each cell holding a socket that grips a bin's foot. The plate carries the full pitch with no clearance subtracted — bins bring their own 0.5 mm — so a 3 × 3 gridfinity baseplate measures 126 × 126 mm and accepts nine 1 × 1 bins, six 1 × 2s, or any mix that covers the cells.
The socket geometry does the holding. Each cell opens into a 37.7 mm straight band that meets the bin's tapered foot, and because every preset uses the same spacing, a gridfinity baseplate printed today still fits bins printed next year — that compatibility is the entire point of the community standard.

How to use this gridfinity baseplate page
- 1
Pick a preset
Choose 1 × 1, 2 × 2, 3 × 3 or 4 × 4; the preview and size panel jump to that plate immediately.
- 2
Check the numbers
Plate width and depth show cells × 42 mm — the 4 × 4 reads 168 × 168 mm — with thickness fixed at 5 mm.
- 3
Switch to Custom if needed
Presets print as-is; choose Custom to reveal X and Y cell fields and set any size the presets skip, like a 4 × 3.
- 4
Download the STL
Each preset exports its own binary STL in millimeters, watertight-validated locally before the download unlocks.
Gridfinity baseplate sizes at a glance
Plate size is pure multiplication — cells × 42 mm per side, nothing subtracted — and thickness stays 5 mm everywhere. The table shows the four presets plus the neighboring sizes Custom reaches; a 4 × 3 gridfinity baseplate, for example, prints 168 × 126 mm.
| Plate | Footprint | 1 × 1 bins held |
|---|---|---|
| 1 × 1 preset | 42 × 42 mm | 1 |
| 2 × 2 preset | 84 × 84 mm | 4 |
| 3 × 3 preset | 126 × 126 mm | 9 |
| 4 × 4 preset | 168 × 168 mm | 16 |
| 4 × 3 via Custom | 168 × 126 mm | 12 |
| Custom gridfinity baseplate | X × Y cells × 42 mm | X × Y |
Why plates subtract nothing and bins subtract 0.5 mm
- The gridfinity baseplate carries the full 42 mm pitch, so identical plates tile one drawer on one shared grid.
- A bin's outer size is cells × 42 − 0.5 mm; the clearance lives in the bin, subtracted once for the whole outline.
- A 1 × 1 bin is 41.5 × 41.5 mm and drops into the 42 × 42 mm socket with 0.25 mm of play per side.
- Socket band: the 37.7 mm straight opening per cell grips the foot below the bin's walls.
Print settings for a gridfinity baseplate
Any preset prints in PLA or PETG at 0.2 mm layers, two perimeters and 15 % infill, socket side up so the 37.7 mm bands keep straight walls. The 4 × 4 uses 168 of a 220 mm bed, so all four presets fit even compact printers. Print every gridfinity baseplate destined for the same drawer in one material, so pitch tolerance stays uniform across the floor.
New to the system? Print the 1 × 1 preset plus one 1 × 1 bin first. If they click together with even friction on all four walls, your printer is on pitch and every larger gridfinity baseplate is safe to run overnight.
Preset plates versus the baseplate generator
This page and the generator page split the job cleanly. Here you grab a standard gridfinity baseplate instantly — four sizes, four files, zero configuration. The generator designs around measurements: cells up to 30, bed and margin inputs, automatic splitting into bed-sized pieces, and a numbered ZIP with an assembly readme for plates like an ALEX drawer's 7 × 12 grid.
Measure first, then choose: if the interior matches a preset, print it here; if not, design it there. The dimensions page converts any cell count to millimeters while you plan, and whichever gridfinity baseplate you start with, the bins come next.

Frequently Asked Questions
What sizes does this gridfinity baseplate page offer?
Four instant presets — 1 × 1, 2 × 2, 3 × 3 and 4 × 4, printing 42, 84, 126 and 168 mm square — plus a Custom option that reveals X and Y cell fields for sizes the presets skip.
Is each preset a different file?
Yes. Every preset generates its own STL with its own socket count — a 2 × 2 gridfinity baseplate is not a cropped 4 × 4 — so cells always land on the true 42 mm pitch.
How thick is a gridfinity baseplate?
5 mm, per the community standard, with a 37.7 mm straight-band socket in each 42 mm cell. That grips bin feet firmly while the plate stays low enough for shallow drawers.
Can these plates tile a large drawer?
Yes. Every gridfinity baseplate keeps the full 42 mm pitch with no clearance, so identical presets sit edge-to-edge on the same grid; for one big auto-split plate, use the gridfinity baseplate generator instead.
