Custom Pipe & Tube Connectors – 90° Angle, T, Cross, 3D Corner & 6-Way, 3D Printed

Custom pipe connectors instead of fixed off-the-shelf sizes

Pipe connectors from hardware stores are usually only made for standardized dimensions like 25x25 mm or 40x40 mm tubing. If you need to join a round pipe or square tube in a size that doesn't match, the right off-the-shelf part is rarely available. The Universal Connector configurator solves that: you enter the profile type, diameter or width and height, insertion depth, wall thickness, and clearance yourself - the connector is generated exactly for your pipe or profile and produced with 3D printing.

90 degree pipe connector for corners and frames

The 90° angle connector is the classic corner joint for frames, racks, and shelving in a single plane. It works for both round pipe and rectangular/square profile, making it a no-weld, no-glue alternative to a corner fitting from a specialty pipe-connector shop.

T-connector for branches and cross braces

For branches, cross braces, or extra support points in a build, the T-connector is the right choice. It joins a continuous pipe with a branch at a right angle - typical for shelf supports, workbenches, or rack frames.

Cross connector (4-way) for flat frame structures

The flat X/Y cross connector joins four pipes or profiles in one plane and is commonly searched for as a 4-way connector. It's suited to grid frames, shelf structures, and flat assemblies where several braces meet at a single node.

3D corner connector for cube frames and shelving

The X/Y/Z 3D corner connector joins three profiles across all three axes at once - ideal for cube frames, shelving units, display cases, or modular building-block systems made from rectangular or square profile.

6-way connector for modular systems

For complex, multi-directional builds, the 6-way connector provides connections in all six spatial directions. It's the part you need for modular rack systems, building-block kits, and larger frame constructions from round pipe where multiple pipes meet at a single node from different directions.

Typical applications

• Industrial-style pipe furniture builds
• Shelving, racks, and workshop structures
• Frames and cube frames for display cases and cabinets
• Prototypes and jig building
• Modular building-block systems
• DIY projects with round pipe or square profile

What material should I use for a pipe connector?

PLA is useful for samples and light indoor use, PETG for tougher builds, and ASA or ABS for higher loads or outdoor use. For load-bearing structures, use a sufficient wall thickness and a longer insertion depth with screw holes enabled.

FAQ

Can I order a pipe connector for my own custom pipe size?

Yes. In the configurator you enter the profile type, diameter or width and height, and insertion depth yourself, and the connector is produced to fit exactly.

Does it work for square tube and rectangular profile too?

Yes. Alongside round pipe, the configurator supports square and rectangular profile with separately adjustable width and height.

Which connector types can I choose?

90° angle, T-connector, flat X/Y cross connector, X/Y/Z 3D corner connector, and 6-way connector.

Can I download the connector as an STL or order it printed directly?

Yes. Once configured, you can use the model for STL download or order the 3D print directly.

Do I need to check dimensions and tolerances before ordering?

Yes, please check dimensions before ordering. Fit, strength, and tolerances depend on material and print settings.
