openGrid bin generator

Good to know

Sizes follow the openGrid grid: 28 mm cells, each bin 0.5 mm under. The back has one openConnect slot per cell in the top row, cut to the openConnect spec with its clearance, so it slides down over the openConnect connectors in your snaps. Pick Multiconnect for slots on 28 mm centres, or Snaps to press it straight into the tile, a snap in each top-row cell.

How it works

1. 1Set the sizes and pick the options: front, label, wall pattern, drain holes, and hangs on. The opengrid bin rebuilds when you let go of a slider.
2. 2Turn it in the preview and check the overall size.
3. 3Download the STL or 3MF, one file per part, and slice it.

What you can change

Width, cells: 1 to 9.

Height, cells: 1 to 6.

Depth: 25 to 150 mm.

Lower the front by: 0 to 120 mm.

Rounded front corners: 0 to 12 mm.

Dividers: 0 to 6.

Scoop at the front: 0 to 15 mm.

Front: Straight step, or Smooth curve.

Label: None, Shelf inside, or Recess on the front.

Wall pattern: Plain, Hexagons, Slots, or Dots.

Hangs on: openConnect slots, Multiconnect slots, or Snaps.

When sizes are not enough

This is a real parametric model, built on a CAD kernel, not a mesh stretched to fit. Walls stay the thickness you set when the opengrid bin grows.

For anything the sliders do not cover, such as ports in the right places, mounting holes, text or a logo, describe it to Voloom. It starts from these sizes and builds the part from scratch.

About STL

STL (Stereolithography). The default 3D printing format since 1987: a bare list of triangles. Every slicer reads it, but it has no units, no color, and no parts.

Units: None in the file. Slicers read the numbers as millimeters. Up axis: Z. Opens in Bambu Studio, PrusaSlicer, Cura, OrcaSlicer, and Blender.

Questions

Is the opengrid bin generator free?

Yes. You get 3 runs a month without an account. Sign in with your email, free, and there is no limit.

Do I need an account?

No. Change the sizes and preview as much as you like. Downloads count toward the free runs; signing in, free, removes the limit.

Can I add cutouts, holes or a logo to the opengrid bin?

Yes. Use “Describe the rest” under the preview. Voloom takes your sizes into a prompt, you add what you need in plain words, and it builds a new parametric model you can keep editing.

Can I get a STEP file?

Yes, from the editor. Open your opengrid bin in Voloom and download STEP on the Maker plan, for Fusion, SolidWorks or FreeCAD.
