A Simpler Way to Work With STL Files
STL File Manager was created to make large STL collections easier to browse and use without adding a complicated new workflow.
The app uses a familiar folder-based layout, provides built-in STL previews, and lets users open one or multiple selected files directly into their preferred slicer.
If you already understand how to browse folders in Windows, you already understand the basic STL File Manager workflow.
Free for Windows 10 and Windows 11Designed Around the Files You Already Have
STL File Manager helps you move from browsing a folder to preparing a print with fewer unnecessary steps.
Browse Your Collection
Open your main STL collection through organized category folders and browse files using a familiar desktop-style layout.
Preview Before Opening
View STL models inside the app before sending them to your slicer. Image and text previews are also supported.
Open Into Your Slicer
Select one STL or multiple STL files and open them directly into your preferred slicer for print preparation.
Your STL Files and Our Printable Tools
STL File Manager keeps your personal collection separate from the managed Printable Tool Set.
My STL Library
My STL Library lets you select your own main STL collection folder and browse its files through the app.
Your personal files remain in their original location. STL File Manager does not move, rename, overwrite, synchronize, or delete them.
Printable Tool Set
STL File Manager also provides access to the Printable Tool Set, a growing collection of more than 80 practical 3D-printable hardware tools like wrenches and pliers.
Free Sample Tools are available through the app with no signup required. The complete collection can be unlocked separately.
