One tube diameter. Multiple angles and CLR ratios. Complete flexibility for your fabrication project.

This 3D printable pie-cut tube mock-up planner bundle gives you a complete collection of available configurations for one metric tube diameter, allowing you to physically plan, test and visualise complex tube layouts before fabrication.

Originally developed for custom exhaust fabrication, the system is also ideal for roll cages, intake and charge piping, custom frames and other tubular fabrication projects.

Simply select your required metric tube OD and receive all successfully validated pie-cut angle and CLR ratio combinations available for that diameter. Multiple segments snap together, allowing you to build complete tube runs and experiment with different bend geometries while checking fitment, clearance and routing before cutting or welding any metal.

Each piece is clearly marked with its diameter, angle and CLR ratio, making configurations easy to identify and helping you transfer your finished mock-up directly to the real fabrication.

One diameter. A complete range of configurations.

Instead of purchasing individual OD, angle and CLR combinations separately, the Single Diameter Bundle gives you the available configuration library for your selected tube diameter.

Print different configurations, compare tighter and wider bend radii and combine different pie-cut geometries while developing your tube route.

Unlike a physical mock-up kit with a fixed number of pieces, you receive the digital models and can print as many mock-up segments as your projects require.

What You’ll Get

✔ Every available configuration for your selected metric tube diameter
✔ Multiple pie-cut angles and CLR ratios
✔ High-quality, print-ready 3D models
✔ Clearly marked diameter, angle and CLR information
✔ 24 rotational alignment positions
✔ Designed to print reliably with standard filaments such as PLA and PETG
✔ Compatible with most FDM 3D printers
✔ Optimized for easy, reliable printing
✔ Recommended print settings and instructions

Snap-Fit Modular Design

Each piece uses a snap-fit connection with 24 rotational positions, spaced at 15° intervals. This allows pieces with different angles and CLR ratios to be combined and rotated while physically planning complex tube routing.

The same connection system is also used by the Futuri Stepped Tube Adapter Mock-up Planner, allowing diameter transitions to be incorporated directly into your mock-up.

Available Metric Diameter Bundles

Each row represents one available Single Diameter Bundle. The angles shown under each CLR ratio are the configurations included for that tube diameter.

CLR Ratio Guide

The centerline radius (CLR) ratio determines the radius created when multiple pie-cut pieces are combined. A lower CLR creates a tighter bend, while a higher CLR produces a larger, more gradual bend radius.

CLR RatioBend Geometry
0.75DVery tight
1.0DTight
1.25DMedium
1.5DLong
2.0DSweeping

CLR is expressed as a multiple of the tube diameter. For example, a 50 mm tube with a 1.5D CLR has a centerline radius of 75 mm.

Print as Many Pieces as You Need

Because these are digital files, you are not limited to a fixed number of physical mock-up pieces. Print the configurations you need in whatever quantities your project requires.

This makes it possible to mock up anything from a single bend to a complete exhaust or tube route before cutting the real material.
