Michael from Teaching Tech made a video guide about the installation. He was so kind to allow me to embed it here! Thumbnail installation starts at 1:49.
Thumbnail generation is based on the fastest STL viewer available. Folders full of STL files are no problem, and most STL thumbnails are generated as fast as those of JPG photos.

Using a peculiar, old-fashioned-looking contraption he claimed was a "time machine," Mr. Yamada and his class found themselves in the middle of a bustling Edo market. Students in period clothing hurried past, oblivious to the visitors from the future. The class watched in awe, taking in the sights and sounds of a bygone era. They saw samurai, merchants, and artisans, all going about their daily lives.
Mr. Yamada was known for his unorthodox methods. His classes were always the talk of the school, not because students found his lessons difficult, but because they found them refreshingly engaging. He taught history, but his approach was anything but traditional. Instead of droning on about dates and events, he brought history to life. genkaku cool na sensei ga
The "time machine" whirred to life, and with a final look at the past, they returned to their classroom. As they settled back into their seats, something was different. The classroom, once a place of mundane learning, had transformed into a portal to the infinite possibilities of the past, present, and future. The class watched in awe, taking in the
One sunny afternoon, while other teachers might have been content with teaching from the textbook, Mr. Yamada decided it was time for a lesson on the Edo period. He didn't just talk about it; he took his students on a field trip... into the past. Yamada was known for his unorthodox methods
In a small, bustling town surrounded by endless rows of cherry blossom trees, there was a high school known for its traditional approach to education. That was until Genkaku Yamada, or simply Mr. Yamada to his students, stepped into the scene. He was unlike any teacher the town had ever seen.
For one student, Taro, this was more than just a fun field trip. He had always struggled with history, finding it dull and irrelevant. But seeing it come alive, experiencing the culture firsthand, something clicked. He realized that history wasn't just about memorizing dates and events; it was about people, their stories, and their impacts on the world today.
Clear your Explorer thumbnail cache (see above) or copy the file to a different location.
This is a bug in Windows 10 that also affects other thumbnails – for example transparent PNG images here and here.
I can’t do anything in my program to work around it, I’m afraid. Please use the Windows 10 feedback function to report this to Microsoft. If enough users do it, they may eventually fix it. Windows 7 does not have this bug.
