Papa’s Best STL Viewer

thingiverse

I've written a lightning-fast STL viewer for Windows that packs a punch without the bloat. It effortlessly opens all STLs - no matter how massive or bizarre they may be. You can easily navigate through folders full of STLs using the left/right arrow keys, just like you would in the Windows Photo Gallery. I've 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're unsure which one to download, simply choose the 32-bit setup. Please don't hesitate to reach out if you encounter any issues or have questions - I'm always refining it!
