Customizable 2&3-Way Connector – Adjustable Angles

A fully parametric 3-way connector with adjustable XY angle, Z tilt, and Z azimuth.
Build any 3-arm geometry you need — from standard 90° joints to complex angled spatial connections. 

The model can also be configured as a 2-arm connector by aligning one arm with another.

Full Angle Control

This version allows independent adjustment of all three arms:

XY angle
Angle between the two horizontal arms, measured counter-clockwise in the XY plane.

Tilt Z
Angle measured from the XY plane towards the +Z axis.
– 0° → horizontal
– 90° → vertical

Azimuth Z
Direction of the Z-arm projected into the XY plane.
– 0° → aligned with first XY arm
– xy_angle / 2 → aligned with XY bisector

See the accompanying pdf or post images for a detailed explanation.

What You Can Build

• Custom tent and canopy structures
• Tubular frames and racks
• Adjustable support brackets
• Experimental geometric constructions
• Compact space-frame joints

From flat Y-splitters to vertical T-joints — and everything in between.

Included 3MF Presets

The provided 3MF file includes ready-to-print examples for rods 10 mm in diameter, demonstrating different angle combinations, such as:

• xy_angle = 90°, tilt_z   = 60°, azimuth_z = 45°
• xy_angle = 120°, tilt_z   = 65°, azimuth_z = 60°
• xy_angle = 135°, tilt_z   = 60°, azimuth_z = 67.5°

Adjustable Parameters

• Rod diameter
• Clearance
• Wall thickness
• Inset length
• Strength ribs (on/off)
• Flat bottom print mode (note it works best for xy_angle < 160°, and should be avoided for larger angles)

The model is written in OpenSCAD and fully parametric. 

Tip: reduce the quality value (for example to 10–30) while adjusting angles to speed up preview, and increase it again before exporting the final STL.

Print Recommendations

Material: PLA or PETG
Nozzle: 0.4 mm
Layer height: 0.2 mm recommended

Supports are required for large tilt configurations.
Flat-bottom mode simplifies printing for angled geometries (xy_angle < 160°).

When using multi-material printing (e.g. PETG support interface with PLA model), expect significantly longer print times due to filament swaps if you use an AMS (but also cleaner print results).
