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.

Marcus’s chair scraped backward. Twelve chapters. Twelve victims. The official count was seven.
“Don’t close your eyes, Naomi. I want you to see the color you turn.”
He picked up his phone to call his captain, but the line was dead. Not disconnected— dead . No dial tone. No static. Just the faint, rhythmic sound of someone breathing on the other end.
He fast-forwarded. Naomi’s face cycled from white to red to the deep, stagnant purple of a bruised plum. At 1 hour, 47 minutes, she stopped breathing. The camera held for another ten seconds. Then a title card appeared, written in elegant serif font: Black.and.Blue.2019.1080p.BluRay.x264-AAA-EtHD-
“For Detective Thorne. You asked for the unedited cut. Chapter 4 of 12.”
The timestamp was today’s date. The thumbnail showed his own living room, shot from the angle of the smoke detector.
The screen went black. Then a single frame flickered to life: a woman’s bare feet, dangling two inches above a dirty tile floor. The camera tilted up. Rope burns. A blue sequined dress. A face he knew—Naomi Cross, the third victim, the one who’d survived long enough to give a description before she bled out in the ER. Marcus’s chair scraped backward
Marcus looked up.
Marcus ran the hash. It matched no known file in any database. But the metadata tag— EtHD —was a signature. He’d seen it before, in the margins of a dark-web forum that vanished hours after the FBI raided it. EtHD stood for “Eternal High Definition.” A joke. The killer’s calling card.
It wasn’t a police file. It was a pirated movie rip. The official count was seven

The little green light on the smoke detector wasn’t blinking green anymore.

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.
