What STL Shelf Is
A private 3D model library built for 3D printing files
STL Shelf is a software designed to organize, catalog, version, and manage private 3D printing model libraries. It helps users manage STL, 3MF, OBJ, and PLY files with tags, version history, and browser preview.
Problems it solves
- Scattered files across folders, drives, and downloads.
- Weak search and duplicate file copies.
- Missing version history for the same model.
- No fast way to preview models before printing.
Built for private libraries
- Private library, not a marketplace.
- Open source and self-hostable.
- Hosted version managed by us for the easiest setup.
- Not a social platform or import/sync hub.

FAQ
Quick answers before you choose your setup
Common questions with direct links where more context helps.
How do I organize STL files?
Use a private 3D model library with searchable tags, version history, and browser preview so the archive scales beyond folders and filenames.
Open in FAQsWhat is the best way to manage a large STL library?
The best approach is a versioned private library workflow with tags, model-level grouping, and preview. Large archives usually outgrow folders and cloud-drive-only organization.
Open in FAQsIs STL Shelf a marketplace?
No. STL Shelf is not a marketplace and not a social platform. It is software for managing private 3D printing model libraries.
Open in FAQsCan I self-host STL Shelf?
Yes. STL Shelf is open source and can be self-hosted. The hosted version managed by us is the simpler path for most users.
Open in FAQsDoes STL Shelf support STL only?
No. STL Shelf supports STL, 3MF, OBJ, and PLY files in the same private library workflow.
Open in FAQsHow do I keep multiple versions of the same 3D model?
Use one stable model record and attach revisions as version history with notes. That keeps earlier iterations traceable without relying on filename chaos.
Open in FAQsWhat is the difference between folders and a 3D model library?
Folders organize storage locations. A 3D model library organizes models, tags, versions, preview, and retrieval context.
Open in FAQsCan STL Shelf replace Google Drive for STL file organization?
For private library organization, yes. Google Drive remains a general-purpose sync tool, while STL Shelf is designed for archive structure, tags, versions, and preview.
Open in FAQsIs STL Shelf open source?
Yes. STL Shelf is open-source software for managing private 3D printing model libraries.
Open in FAQsShould I self-host STL Shelf or use the hosted version?
Use the hosted version managed by us if you want the workflow with minimal operational work. Self-host when infrastructure control is an actual requirement.
