Getting started
Download
The ZIP archive you receive after downloading a model contains the following files:
- One or more 3D files in STL or 3MF format, compatible with common slicers (Cura, PrusaSlicer, Bambu Studio, etc).
- A "values-model" file
- A "license" file
- A "download-hash" file
The dd suffix found in some filenames and in the ZIP archive name, for example dd840, refers to the download ID, which in this example is number 840. Each download is assigned a unique dd suffix.
Each file serves a purpose. Make sure to keep them all.
STL or 3MF 3D File(s)
STL is the "classic" 3D printing format. 3MF is a more recent format that includes more information and capabilities than STL.
"values-model" File
The "values-model" file lists the parameter values of the downloaded 3D model. For example:
#1 width: 50 mm
#2 length: 140 mm
#3 thickness: 20 mm
#4 shape (0:square,1:circle): 0
#5 transition (0:right,1:rounded): 1
#6 fillet radius: 0 mm
#7 hole diameter: 4 mm
To see the full details of these parameters, you can search for the model by ID and view each parameter in the "Parameter Illustration" section.
"license" File
This file specifies the license associated with your download. It is therefore especially important.
A link to the official license description is included.
You can also visit our license page.
"download-hash" File
This file contains a fingerprint of your download’s attributes. It serves as a verification code for the authenticity of your download.
As mentioned above, each file matters. Make sure to keep the entire ZIP archive.
Concepts: Template, Parameter, and Model
The concepts of template, parameter, and model are central on iteration3d.fr.
A template is like a pattern or a descriptive mold defining one or more 3D shapes forming a cohesive unit.
This "mold" has characteristics that can be adjusted. This is where the concept of parameters comes in: each template includes parameters whose values can be customized.
A model is the result of applying specific values to a template. Therefore, an infinite number of models can theoretically be created from a single template.
Note that a model can consist of multiple objects. A good example is a case consisting of a base (the "box") and a lid.
Model Search
Search by Parameter Values
Each template page lets you search for models based on specific parameter values. Please note that not all parameters may be available for search.
For each searchable parameter, the minimum and maximum values are displayed. These values reflect the range of models currently available in the database.
Results are ranked from most relevant to least. If a model exactly matches your criteria, a star will appear.
You are not required to fill in all parameters—far from it. If no relevant results are found, try again by entering only the most important parameters for your needs.
Search by Identifier
Searching by model ID is useful if someone has shared just the model number with you (e.g., #800), or if you want to view the parameter breakdown after downloading a model.
The ID search lets you retrieve the meaning of each value (#1, #2, etc.).
ID-based search is available on this page.
