Printing Recommendations:

For printing, the print profile with the desired round bar diameter can be selected (e.g., 6mm profiles). The connectors are distributed across individual plates. The desired number of connectors can be obtained using the "duplicate" function.

Materials:

• Smooth dowel rods made of beech wood are suitable as round bars (tested 6mm, 8mm, and 15mm).
• For screwing, M3 wood screws without shaft and with countersunk head are suitable. The length should be at least ½ of the diameter.
• A thin steel wire rope (1-2mm) can be used for tensile force absorption. 

To test this model when a suitable round rod is not available, or for decorative purposes, you can use the following printable round rod. (Not for strength-related applications!):

Community:

I appreciate the community aspect of 3D printing and am pleased to share my models for everyone to use.

If you decide to print connectors, I invite you to share pictures of your finished models. Seeing how others utilize these designs can be beneficial for everyone. I also encourage you to provide feedback on the included print profiles. Your experiences and suggestions can help improve the designs and assist others in achieving better results.

If the desired diameter is not available:
To adjust the diameter for the pipe connection, you can modify the expression named "shaft_diameter_measured" in the Customizer.
