Just added!

On-demand generation is now up and running for the inline tube adapter template!

Feel free to try it out and share your feedback.

It means the on-demand generation mechanism is now in place!

Coming soon: new and more complex designs — still fully customizable on demand!

More than 300 STL models are available for free download!

As you’ve probably guessed, the goal is to multiply templates and build a large library of parameterized 3D files (STL/3MF) compatible with Cura, PrusaSlicer, Bambu Studio, or any other slicing software for 3D printers. How? See this page: How are 3D files generated?

What’s new? To keep it simple, iteration3d.fr aims to become a platform for technical 3D files available in various dimensions, and fullly configurable!

If you like the idea, don’t hesitate to spread the word or leave us a quick message of support!

Just added: a new template for inline tube adapters!

2025-06-17 · New templates · sylvain

New on iteration3d.fr: create your own inline tube adapters!

Generate on demand custom connectors between two tubes of different diameters, perfectly aligned… or deliberately offset.

Set the lengths, diameters, and thicknesses of each tube, adjust the transition between them, apply an optional axis offset, and add fillets to the ends to ease insertion.

Thanks to a robust modeling process, transitions are optimized and fillets are automatically adapted to the geometry.

A custom connector, ready to print, in just a few clicks!
