Design modular furniture online, then generate the parts needed to build it.

A furniture builder made for actually making the result

Many 3D design tools stop at the visual model. HexaNect is built around the next step: turning a modular design into physical boards and printable joints. As you create a structure, the builder tracks the actual boards, determines the connector geometry at each junction and prepares manufacturing information for export.

You do not need to install CAD software or OpenSCAD. The builder runs in a modern web browser, and connector mesh generation runs locally through OpenSCAD WebAssembly.

Free to use during the public beta

HexaNect is currently free to use and does not require an account. The goal is to make it easy to experiment with modular furniture before committing material or print time.

You can start from a simple structure or one of the example designs, change the dimensions, add or remove cells, create shelves, configure the connector fit and then export the final build package. The important design information stays in the project file so a build can be reopened and edited later.

Useful for more than shelves

The honeycomb language works naturally for shelving, but the builder can also be used for entryway tables, nightstands, console tables, shoe storage, record storage, plant stands, display furniture and other custom household pieces.

The intended territory is practical maker furniture with reasonable household loads. It is not meant to replace heavy-duty garage shelving, structural framing or other safety-critical construction.

Check proportions before cutting plywood

Scene mode is included because dimensions that look reasonable on a screen can feel completely different in a room. Familiar objects such as books, shoes, bottles, plants and electronics can be placed on the design to help understand real-world scale.

Scene objects are presentation tools rather than manufacturing parts. The furniture geometry remains the source of truth for the cut list and connectors.

The connectors are designed to be printed the right way

Connector strength is not just about material. FDM parts are directional, so HexaNect connector geometry is designed around an intended print orientation that places the printed layers favorably for the forces expected in use.

The same geometry also aims to stay easy to manufacture, avoiding unnecessary supports and difficult overhangs where possible. PLA, PETG and ABS can all be suitable; PETG is the material I personally use most often, while PLA works fine for many indoor projects.

What the builder exports

• Unique 3D-printable connector STL files used by the design.
• Connector quantities and a board bill of materials.
• Board cut information in metric and imperial units.
• An assembly guide for the finished structure.
• A link and one-click HTML file for reopening the exact editable build.
• A clean Scene preview image when Scene decor is present.

For standard honeycomb structures, friction fit has proven surprisingly strong in hands-on testing. If a joint feels a little loose, a thin painter's-tape shim is an easy reversible fix, while adhesive can be used selectively for permanent assembly.
