STEMFIE File-Naming Convention

The files in the STEMFIE construction set follow a standardized naming convention as detailed below:

Naming Convention Structure

Part typeStructure VariationsDimension - Unique STEMFIE Part Number(Project Home URL).filetype

  Part Type  

This component describes the category of the part, such as beams, braces, fasteners, springs, or washers.

  Structure Variations  

These abbreviations represent specific design features of the part, such as square or rounded ends, joint types, or other variations.

  Dimensions  

Indicates the part’s size in STEMFIE Block Units (BU = 12.5 mm), typically formatted as Length x Width x Height x Variations. To ensure clear sequential listing, values include trailing zeros. Some dimensions may also be specified in millimeters (mm).

  Unique STEMFIE Number  

A unique identifier classifies each item:

• SPN: STEMFIE Part Number
• SPS: STEMFIE Project Set
• SCT: STEMFIE Construction Template

  Project Home URL  

The URL directs users to the STEMFIE project’s homepage.

  Filetype  

Defines the file format, such as .FCStd, .stl, .stepz, .step, .svg, or .pdf

Folder Structure

The official STEMFIE file repository at get.stemfie.org provides a well-structured collection of STEMFIE part files. Each folder is named descriptively, indicating the type of part it contains, such as "Beams - Angled - T-shaped Symmetric - Square Ends." Within each folder, files are organized by their unique STEMFIE Part Number (SPN) and are available in multiple formats, including .3mf, .step, and .jpg.

Thumbnail images accompany the 3D files for quick reference. Each part includes a unique thumbnail matching its file name. Additionally, a general folder thumbnail is labeled as "- *** (thumbnail).jpg." This structure ensures easy navigation and accessibility for users.

Example:

• Beams - Angled - T-shaped Symmetric - Square Ends   ← folder
  • - Beam AGD TSH SYM ESS (thumbnail).jpg   ← part type thumbnail
  • Beam AGD TSH SYM ESS BU03x05x01 - SPN-BEM-1003 (stemfie.org).3mf   ← 3D-printing file
  • Beam AGD TSH SYM ESS BU03x05x01 - SPN-BEM-1003 (stemfie.org).step   ← CAD file
  • Beam AGD TSH SYM ESS BU03x05x01 - SPN-BEM-1003 (stemfie.org).jpg   ← part thumbnail
  • Beam AGD TSH SYM ESS BU03x05x01 - SPN-BEM-1003 (stemfie.org).stpZ   ← CAD file
  • Beam AGD TSH SYM ESS BU03x05x01 - SPN-BEM-1003 (stemfie.org).stl   ← 3D-printing file
