Hale Library 3D-Printed Spacers

This repository contains 3D-printable spacers used to connect the cube riser panels in Hale Library at Kansas State University. Each design is available as an STL file for slicing and a GLB file for browser-based preview.

About this example repository

This is both a working collection of 3D models and a deliberately small example of how a research or creative project can be organized on GitHub. The project files make the spacers usable; the surrounding documentation makes the project understandable, citable, reusable, and open to contribution.

See Repository anatomy: why these files exist for a plain-language explanation of the README, license, DOI, CITATION.cff, releases, contribution files, issue and pull-request templates, and automated checks. Not every repository needs every one of these features, but each should be included or omitted intentionally.

Choose a spacer

Design	Intended use	Model files	Editable CAD
spacer_cube_riser_180_0	Connects two riser panels at the top	STL · GLB	Tinkercad
spacer_cube_riser_180_1	Connects two riser panels at the top; includes embellishment triangles	STL · GLB	Tinkercad
spacer_cube_riser_360	Finishes the end of a riser panel at the top	STL · GLB	Tinkercad
spacer_cube_riser_90_0	Connects two panels at 90 degrees when one is slightly lower	STL · GLB	Tinkercad
spacer_cube_riser_90_1	Connects two panels at 90 degrees at any height	STL · GLB	Tinkercad
spacer_cube_riser_90_2	Alternate form of 90_0; includes embellishment triangles	STL · GLB	Tinkercad

Use the models

1. Open a GLB file above to inspect the model in GitHub's 3D viewer.
2. Download the matching STL file and open it in your slicer.
3. Import the model in millimeters if the slicer asks for units; STL files do not store unit information.
4. Check the orientation, supports, material, and other print settings for your printer.
5. Print one copy and test the fit before producing a full set.

Printer tolerances and materials vary, so this repository does not prescribe a universal slicer profile. If you find settings that work reliably, please share them in an issue or pull request.

Contribute

Problems, improved models, and new spacer designs are welcome. Start with the contribution guide, then use an issue template or open a pull request. New or modified designs should normally include:

• matching STL and GLB files;
• a link to the editable CAD source;
• a short explanation of the use case; and
• the results of any digital or physical fit checks.

The repository's automated check confirms that model pairs are present and that their basic file structures are valid. Run it locally with:

python3 scripts/validate_models.py
