I’ve written a fast STL viewer for Windows. It comes without bloat and opens all STLs – no matter how big or how strange they are.

You can easily browse folders full of STLs using the left/right arrow keys, much like the Windows Photo Gallery.

I uploaded 32-bit and 64-bit versions, an installer and a portable version (if you want to copy the viewer to your USB drive or to your local network).

If you don’t know what to download, just choose the 32-bit setup.

Please contact me if you encounter any issues or if it raises any questions – I’m always improving it!
