There is soon a new STL thumbnail Provider

With the help from RonGeorge I got som STL that was complex and crashed Windows File Explorer.

After some testing I was able to get all file rendered to thumbnails.

It was not so easy to just replace the DLL. I had to do a total new MSI file.

After that RonGeorg has confirmed that this is working it will be available at

The build-in AutoUpdater should see that a newer version is available and try to download and install that version. If this is working there is no need to do the manual download and install.
