Two standards, both drawn to the spec.

Cubby generates to the published standards — the Gridfinity 42 mm grid and the Festool SysOrg 25 mm grid — the way a datasheet would draw them. Pick a standard, dial the parameters, export.

Gridfinity · 42 mm grid
42 mm3 u
FIG 1.1
42 mm grid footprint

Gridfinity bins snap to the 42 mm cell pitch — a 2×3 footprint drops cleanly into any standard baseplate.

7 mmSECTION A–A · 6 height units
FIG 1.2
7 mm height units

Depth is set in 7 mm increments. The base profile and stacking lip stay true to spec at every height.

⌀6×2 mmEXPLODED · base + bore
FIG 1.3
Base hardware

Optional 6×2 mm magnet bores and M3 screw counterbores, placed exactly where the standard expects them.

Festool SysOrg · 25 mm grid
25 mm2 u
FIG 2.1
25 mm SysOrg grid

Festool / TANOS Systainer organizers run on the finer 25 mm grid — a 3×2 tray cluster fits the standard insert footprint.

68 mmSECTION B–B · proud shoulder
FIG 2.2
TANOS 68 mm shoulder

A draft-tapered body with the proud stacking shoulder at TANOS 68 mm default — so trays nest and seat inside the Systainer.

rib pitchBOTTOM · waffle foot
FIG 2.3
Waffle-grid foot

The underside carries a waffle-grid foot for stiffness and grip — the detail that keeps a thin-wall tray rigid in use.

Every parameter, with the dimension attached.

No guessing, no fudge factors. Change a value and watch the geometry — and the numbers — update in the same breath.

Parameter inspector

Steppers, sliders, and toggles — every one in real units.

Grouped, collapsible controls with progressive disclosure: advanced parameters stay out of the way until they matter. Each value carries its unit suffix in mono, so what you read is what gets cut.

  • Numeric steppers with a mono unit suffix
  • Dependent params reveal only when relevant
  • Every edit re-meshes the viewport in ~150 ms

Questions, answered.

Do I need to install anything?

No. The generator runs entirely in your browser — nothing to download, works on macOS, Windows, and Linux.

Is the geometry actually print-ready?

Yes. Every export is a watertight, manifold mesh aligned to the build plate — a closed floor and closed feet, never an open shell. Export an STL and slice it directly.

Which standards does Cubby generate?

Two: the Gridfinity bin and baseplate on the 42 mm grid with 7 mm height units, and the Festool SysOrg organizer on the 25 mm grid. Parts interlock with any compliant baseplate or Systainer.

Can I tune tolerances for my printer?

Yes. Set fit clearance from 0.25 mm snug to 0.75 mm loose, and adjust wall thickness to match your perimeters.

What happens to my saved models?

They sync to your account and stay editable forever. Downgrade and your models are read-only until you re-upgrade — never deleted.

Can my makerspace use it as a team?

The Studio plan includes a shared library with 10 seats. Educational makerspaces can email us for a free Studio seat.
