Snap-Fit Modular Design
The individual pie-cut sections are designed to snap together, allowing you to quickly add, remove and rotate segments while experimenting with different tube routes.

Each pie cut features 24 equally spaced rotational notches, with every notch representing exactly 15° of rotation. This makes it easy to accurately control and repeat the rotation between individual segments when creating complex three-dimensional tube routes.

CLR Ratio Guide
The CLR (Centerline Radius) ratio determines the bend radius relative to the tube outside diameter. A lower ratio creates a tighter bend, while a higher ratio creates a more gradual bend.

For example, a 50 mm tube with a 1.5D CLR has a centerline radius of 75 mm.

Custom sizing option
Can’t find the combination you need? Select the Custom Size option and provide your required OD, Angle and CLR ratio. Your custom file will be manually created to your requested dimensions and sent to you once completed.

What you’ll get

Instant download
For standard configurations, your files are generated based on your selected OD, angle and CLR ratio and made available digitally so you can start printing right away.

Custom Size orders are manually created to your requested dimensions and will therefore not be available as an immediate download.

Important
This is a digital product, not a physical item.
No product will be shipped. A 3D printer is required to create the tool yourself.

Personal-Use License
Your purchase includes a personal, non-commercial license. You may print the design as many times as you like for yourself, friends and family, provided the prints are supplied free of charge.

The digital files may not be shared, redistributed or resold, and physical prints may not be sold or used commercially.

Each file is individually digitally watermarked upon generation/download, allowing unauthorized distribution to be traced back to the original purchase.
