Does anyone know of, or is using, a .stl thumbnail viewer for Windows(11)? I’ve run a across a few like Papa’s Best STL Thumbnails (papas-best.com) and it passes my Norton Scan but Windows does not want to install it.
Windows Powertoys can display thumbnails embedded in the gocde file in windows Explorer if that is of use? Otherwise you could just open the stl in the windows 3d viewer

Powertoys is exactly what I’m looking for. It displays the thumbnail in a large window without having to open it in a slicer or app. Thank you!
