Gridfinity Gen
Gridfinity Gen is the shortest route on this site between an idea and a printable file. Pick bin or baseplate, set X cells, Y cells and height in U units, press download — that is the whole interface. No wall-thickness sliders, no divider grids, no decisions you did not ask for; just the community 42 mm geometry and a watertight STL in millimeters. That is all Gridfinity Gen asks of you.
The page exists because of how people actually search: many type gridfinity gen and want a file immediately, not a tour of parameters. For that mood, three numbers are plenty — a 2 × 3 bin at 4U already handles a surprising amount of workshop storage. Everything the deeper editors offer stays one click away for the day a print needs it.
Nothing is dumbed down behind the simplicity. Gridfinity Gen runs the same local geometry engine as the full editors, validates the mesh for watertightness before the download unlocks, and writes a binary STL in millimeters. The output is identical in quality; only the number of controls shrinks.
What Gridfinity Gen asks for
Four inputs, nothing hiding behind a second screen. Type selects bin or baseplate; X and Y set the cell footprint; the U field sets height for bins. The dimensions panel converts everything to millimeters live, so a 2 × 3 selection immediately reads 83.5 × 125.5 mm with the 0.5 mm outline clearance already applied — Gridfinity Gen never makes you do that arithmetic in your head.
| Field | Accepts | Example |
|---|---|---|
| Type | Bin or baseplate | Bin |
| X cells | 1 to 12 | 2 |
| Y cells | 1 to 12 | 3 |
| Height | 2U to 12U, bins only | 4U |
Gridfinity Gen versus the full generator and the maker
Three doors lead to the same geometry. Gridfinity Gen asks for the minimum and hides every advanced option on purpose. The full generator exposes wall thickness, floor thickness, dividers, stacking lips and magnet pockets for people who tune to the millimeter. The maker starts from template cards — bin, baseplate, socket organizer — and reveals parameters one screen at a time. Choose by mood: certain, curious, or somewhere between, and let Gridfinity Gen carry you when speed is the whole point.
From zero to STL with Gridfinity Gen
- 1
Choose bin or baseplate
One toggle decides which community part you are making; the height field appears for bins.
- 2
Type three numbers
X cells, Y cells, height in U. The panel shows millimeters live: 2 × 3 at 4U is 83.5 × 125.5 mm standing 28 mm tall.
- 3
Glance at the preview
Spin the model to confirm proportions — the numbers on screen are the numbers in the file.
- 4
Download
The STL is written locally after a watertight check — no upload, no queue, no account.
Because there are no detours, the whole loop fits inside a minute: decide, type, download, slice. Gridfinity Gen earns its keep on the second and tenth print of a known-good size, where re-opening deep editors would only slow you down.
The math Gridfinity Gen runs for you
- Pitch: every cell is 42 mm on both axes; a bin's outline is cells × 42 with 0.5 mm subtracted once for the whole footprint.
- Height: 1U equals 7 mm and already includes the 4.75 mm foot, so 6U stands 42 mm — 45.8 mm with the stacking lip.
- Baseplates: cells × 42 with no clearance, 5 mm thick — a 4 × 3 plate is 168 × 126 mm.
- Export: binary STL in millimeters — the Gridfinity Gen download is validated in your browser, never a second-class file.
Those are the only formulas behind the screen. Gridfinity Gen evaluates them on every keystroke, which is why the preview never lags and the downloaded file never surprises you with a different size than the one you configured.
When Gridfinity Gen is the right tool
Reach for it when the decision is already made: you know a 1 × 1 bin fits that screw assortment, you need one more 4 × 3 baseplate to finish a drawer, or you are reprinting a proven size in a new color. Reach deeper when the question is still open — custom walls for heavy tools, dividers for a parts kit, pockets for 6 × 2 mm magnets. Gridfinity Gen is the front door, not the whole house.
- First contact: print one 1 × 1 bin and one 1 × 1 baseplate to learn how the community foot feels on your printer.
- Refill: sizes you have already proven reprint identically through Gridfinity Gen, since the math never drifts between sessions.
- Prototype: a quick block from Gridfinity Gen to test a layout idea before investing deep customization elsewhere.
If you typed gridfinity gen into a search box and landed here, the shortest possible next step is: bin, 2, 3, 4U, download. One test print later you will know exactly how the community standard feels on your machine.

Frequently Asked Questions
What does Gridfinity Gen mean?
It is shorthand — gridfinity gen is simply how many people abbreviate the search when they want a file fast. This page answers that intent with the fewest fields that still produce a correct part.
Is Gridfinity Gen a different tool from the full generator?
No. Same engine, same community geometry, same watertight export. Gridfinity Gen simply shows four fields and hides the advanced options the full generator exposes.
Can I add dividers or magnet pockets here?
Not on this screen; Gridfinity Gen keeps the surface minimal by design. Open the full bin generator or the maker when a print needs dividers, a stacking lip or Ø6.5 × 2.4 mm magnet pockets.
Is Gridfinity Gen free?
Completely. Like every tool on this site it runs in your browser, generates files locally and puts no limit on downloads — no account required.
