The STL viewer for Mac that shows your whole library.

HEXOstudios renders every STL file on your Mac as a 3D thumbnail and previews it in 3D, so you find the print you want by what it looks like, not by what it’s called.

A HEXOstudios library of STL files: fifteen 3D print models shown as rendered model cards, each with its name, size and STL badge
A real HEXOstudios library: every card is the model itself, rendered on the Mac
01 · SEE EVERY STL

Every STL, rendered as the print it is.

A folder of STL files is a list of names. HEXOstudios turns it into a library you can see: each file becomes a card showing the model itself, so a dragon looks like a dragon and a bracket looks like a bracket, even when the file is called final_v3_fixed.stl.

Rendered thumbnails for every STL

Import a file or a folder and HEXOstudios renders a thumbnail for each STL, right on your Mac. There’s no limit on how many, even on Free.

Find it without hunting for it

Smart Search filters your whole library by name, file type, folder or tag, and understands words like “favorites”, “this week” or “large”. Batch Rename gives many files new library names in one pass. Both are free.

Your files stay where they are

HEXOstudios works with your STL files where they already live, on your Mac or on an external drive, and never copies them into itself. It has no network access of its own, so nothing is ever uploaded.

02 · PREVIEW IN 3D

Check a model in 3D before you slice it.

A thumbnail tells you which file it is. A 3D preview tells you whether it’s the right one: the orientation, the proportions, the detail you remember.

3D preview, free

Select an STL and preview it in 3D inside the library: spin it, or switch between Solid and Mesh views. Unlimited STL previews are part of HEXOstudios Free, together with OBJ, PLY, AMF and USDZ.

Full 3D Preview PRO

Open any model full-screen in 3D with orbit and zoom. The same view covers every format HEXOstudios supports, and G-code files open as a toolpath view with their print details.

A viewer, not a slicer

HEXOstudios organizes and previews your files; it doesn’t slice them or control printers. When a model is ready, Send to Slicer hands it to the slicer you already use.

03 · ORGANIZE

From a downloads folder to a library.

Folders that work the way you do

On Free, import files or a folder of files, sort models into your own folders and star your favorites. With Pro, bring in whole folder trees at once, 200,000+ files in a single import, with their subfolders kept as your library’s structure, up to three levels deep.

Big collections welcome

Your library has no limit on how many files it holds, even on Free. If your STL collection runs to thousands of files across several drives, read how HEXOstudios handles large 3D libraries.

Keep it clean PRO

Library Health scans the whole library for duplicate entries and oversized files, and removes them from your library in a click. Your files on disk are never touched.
