Just added: a new template for inline tube adapters!

2025-06-17 Category: 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!

Let’s dive into on-demand 3D compartment box files!

2025-06-07 Category: New templates Sylvain

On-demand generation of compartment boxes is now available on iteration3D.fr !

Set the number of rows and columns, adjust the length, width, and height of the compartments, choose the wall thickness… and get the box you’ve been needing all along.

Certain parameter combinations even allow for original shapes, like almost cylindrical cavities.

Everything’s ready to meet your needs and generate your ideal box in just a few clicks!

What is the STL 3D file format ?

2025-05-18 Category: 3D Modeling Sylvain

Do you often use STL files without really knowing what's inside them? This iconic format of 3D printing has existed since 1987… yet it still remains the undisputed standard today.

Discover the origin of the format, how it works based on a triangle mesh, and why it's so universally adopted.

Did you know that a simple fillet can multiply a file's size by 400? Or that just a few lines of text can generate a perfect cube?

Finally, understand its limitations… and why, despite them, it still dominates over newer formats. A complete, illustrated, and accessible article.
