Parametric Pipe & Connector System

A scalable parametric conduit system for cables, purge routing, and more — built for reliability, not compromise.

This is a fully parametric pipe and connector system designed as a scalable alternative to segmented flexible hoses.

The original concept explored a flexible segmented design, however issues with strength, fit, and tolerance meant the segments could separate under their own weight. This design pivots to a more reliable pipe + barbed connector approach, improving consistency, strength, and usability.

Design Overview

The system consists of:

• Parametric straight pipe
• Barbed connectors in:
  • Straight
  • 30°
  • 45°
  • 90°

All components are generated from a single model and can be customised to suit your application.

Parameters

• ID (Internal Diameter) – Pipe internal diameter (mm)
• Length – Pipe length (mm)
• Tolerance – Clearance between pipe and connector (mm)

Tolerance Guidelines:

• Minimum: 0.10 mm (too tight below this)
• Maximum: 0.20 mm (too loose above this)
• Recommended: 0.14 mm

Sizing

Pipe length can be scaled from 50 mm up to your printer’s maximum build volume:

• X1 / P1 Series: ~250 mm
• X2 Series: ~260 mm
• H2 Series: ~320 mm
• A1 Mini compatible (size limited)

Printing Notes

• Pipes are designed with thin walls to minimise filament usage
• Connectors should be printed on their side for best strength and fit
  • Supports required
• Pipes can be printed upright

TPU can be used for the pipe to allow flexibility where required.

Use Cases

• Cable management / conduit
• Diverting printer purge material
• General routing applications
• Light-duty garden use (material dependent)

For water use:

• Consider using PTFE (plumber’s) tape to improve sealing

Design Intent

This system prioritises:

• Reliable connections
• Consistent tolerances
• Ease of printing
• Scalability

While less modular than segmented hoses, it provides a far more dependable solution for real-world use.
