Snap-Fit Modular Design
Each piece uses a snap-fit connection with 24 rotational positions, spaced at 15° intervals. This allows different pieces to be connected and rotated relative to each other 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 the same mock-up system.

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 Ratio | Bend Geometry |
|---|---|
| 0.75D | Very tight |
| 1.0D | Tight |
| 1.25D | Medium |
| 1.5D | Long |
| 2.0D | Sweeping |
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, while a 2.000″ tube with a 1.5D CLR has a centerline radius of 3.000″.
Print as Many Pieces as You Need
Unlike a physical exhaust mock-up kit with a fixed number of pieces, the Complete Bundle gives you the digital models themselves.
Print whichever diameters, angles and CLR configurations you need, whenever you need them, and produce as many physical mock-up pieces as required for your own projects and fabrication work.
This allows you to build anything from a single test bend to a complete exhaust, intake or tubular route without being limited by the number of pieces in a physical kit.

Digital Product & License
This is a digital product, not a physical item. No product will be shipped. A 3D printer is required to create the tools yourself.
The files may be used for personal projects as well as professional and commercial work. You may print the designs as many times as needed for your own projects and fabrication work.
The digital files themselves may not be shared, redistributed, uploaded, copied for others or resold. All intellectual property rights remain with Futuri Motion Tech.
Each file is individually digitally watermarked upon generation/download, allowing unauthorized distribution to be traced back to the original purchase.
