Snap-in Pipe Clamps (Rev. B) – 20-200mm – 0.8-5.5in

Welcome to the improved revision of my snap-in pipe clamp design, now with more diameters and additional wall distances! This versatile design is optimized for the FFF process with various filaments, ensuring a quick print without supports while using minimal material. The result is a functional and robust part.

When printed with PETG or ASA, the clamping force is sufficient to hold pipes along a wall without any additional fasteners. For ceiling mount or heavy pipes, there are openings for securing the clamp using a zip tie.

This project page features the improved revision B of the design. Please note that the dimensions are not the same as revision A, but you can still download the older models from the original page.

Update 2024-08-13: I added an example design for Fusion where you can see how these kind of clamps are made. See file Clamp Extrusion Example.f3d at the end of the model files section.

How to Print the Pipe Clamp

A Prusa Slicer example project, LR2209B-… Print.3mf, is available with all recommended settings. Feel free to use this, or refer to the table below:

A Note on Using PLA for These Clamps

While PLA can be used, it may not be the ideal material for this model. Use PLA at your own risk, as parts printed with PLA may break or deform over time. For very light loads or decorative purposes, PLA might be suitable.

Dimensions

The part number and file name follow this format:

LR2209-P<...>-H<...>-W<...>-D<...>.3mf

Pipe Diameter (D)

The pipe diameter is specified with a number and its unit. A range of metric and imperial pipe sizes is available.

These values cover a wide array of standard pipe diameters. The seemingly unusual numbers are due to the imperial sizes being based on NPS values, while the metric ones are roughly based on DN-values for plastic pipes.

Wall Distance (W)

The wall distance is specified in millimeters. It represents the distance between the pipe and the wall after installation.

Profile Width (H)

The profile width is specified in millimeters. All models on this project page have a width of 20mm.

Profile Thickness (P)

The profile thickness is represented by a symbolic number. All models on this project page have a thickness of 2, which is equal to 2.54mm.

Catalogue PDF with Detailed Model Information

A comprehensive catalogue PDF is available for this project, providing a handy reference for all model files. The catalogue includes illustrations and detailed information for each file, along with dimensions and helpful tables to quickly find the perfect model for your specific requirements. This valuable resource allows you to easily browse through the collection and select the most suitable clamp for your needs.

You find the PDF with catalogue in the “other files” section.

Example Design for Fusion

In the model file section, you’ll find the file Clamp Extrusion Example.f3d for Fusion. It demonstrates how to create this type of clamp and provides a good starting point if you would like to integrate these clamps into your own designs.

How to Use the Pipe Clamp

To ensure even pressure distribution under the screw head, slide a metal washer from the side and fasten the wood screw as shown in the image below. This prevents the screw head from sinking into the hole and generating side forces that could cause cracks along the printed layers.

To make the most of this pipe clamp, please follow these recommendations:

• Always use screws with lens, flat, or round heads.
• Do not use countersink screws.
• Always place a metal washer under the screw.
• Use a washer that ideally covers as much of the flat area as possible.
• Do not overtighten the zip tie. It's meant to keep the clamp closed, not to generate pressure. Conclusion

I hope this improved revision of the pipe clamps, along with the additional wall distances, offers you more flexibility when fastening pipes to a wall. If you find this print useful, please consider rating it and sharing photos of how you've used the clamps.

Happy printing!
