Why: For my DIY chicken/duck coop build I needed a multi-directional hub to join five pieces of 20 mm PVC at right angles. This 5-way connector lets you build more complex frames and corners without multiple separate fittings. It has a flat back for easy bed adhesion or optional mounting to a flat surface.

Design Notes

4-way, 90° connector for 20 mm PVC pipe.

Perfect for making cube corners, cross-braces, or roof structures.

Print-in-place – no assembly required.

Not designed for pressurised water flow (framing use only), but if you test it with water successfully, let me know!

Snug fit keeps structures rigid.

Flat back makes it easy to screw or glue to wood, walls, etc.

Printing Specs (my test):

Printer: Creality K1 SE

Material: PLA Rapid+ from Deeplee and PTEG Rapid + ******

Layer height: 0.2 mm

Standard 0.4 mm nozzle

Speed: max setting

No supports, no raft or brim required

I printed multiple connectors in one run without issues.

Use Cases:

Great for chicken/duck coops, garden frames, cube-style storage racks, or any PVC project needing a solid 5-way right-angle joint. Or garden irrigation.
