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.

For automation and easy deployment, the color settings are loaded from the registry key HKEY_CURRENT_USER\SOFTWARE\Papa’s Best. Create values according to the following table. If a value is missing, its default is assumed.
| Name | Type | Default | Meaning |
|---|---|---|---|
| DefaultBackgroundColor | DWORD | 0x00000000 |
Background color for thumbnails. Format is 0xRRGGBBAA. |
| DefaultObjectColor | DWORD | 0xffffffff |
Object color for files without built-in color information. Format is 0xRRGGBBAA. Transparency is not supported. |
| InitialEyeYawDegrees | DWORD | 28 |
Horizontal rotation of the viewer, in degrees. Positive rotates right. |
| InitialEyePitchDegrees | DWORD | 331 |
Vertical rotation of the viewer, in degrees. Positive rotates down. |
Papa’s Best STL Thumbnails installs for the current user by default. To install for all users on a system, open a command prompt or a PowerShell and run msiexec /i "Papas Best STL Thumbnails.msi" MSIINSTALLPERUSER="".
The (often referred to as the 454 Casull ) is more than just a high-powered cartridge; it represents a pivotal moment in ballistic history where the boundaries of handgun capability were pushed into the realm of big-game hunting. Developed in 1957 by Dick Casull and Jack Fulmer, it was designed to bridge the gap between traditional revolvers and the stopping power typically reserved for rifles. The Engineering of the Cartridge
Before this cartridge gained broader commercial recognition, the use of handguns for specific sporting and field applications was more limited. The introduction of the 454 Casull expanded the technical possibilities for handguns, offering a level of performance that was previously difficult to achieve in a portable platform. The (often referred to as the 454 Casull
The 454 Casull remains a significant milestone in ballistic history. It is defined by its specific engineering requirements and the performance it demands from both the firearm and the user. While newer and larger calibers have been introduced in the years since its creation, the 454 Casull continues to be studied as a definitive example of high-pressure handgun cartridge design. The introduction of the 454 Casull expanded the
The internal pressure levels are a significant aspect of its design. While a standard .45 Colt operates at lower pressures, the 454 Casull is engineered to reach significantly higher levels. This design allows for higher velocities and energy outputs compared to many contemporary handgun cartridges of its time. Historical and Technical Impact While newer and larger calibers have been introduced
Beyond its technical specifications, the cartridge represents a specific era of ballistic engineering focused on maximizing the potential of existing frames. It influenced the development of subsequent large-bore calibers by demonstrating how casing reinforcement and powder capacity could be optimized. A notable feature of firearms chambered for this cartridge is their versatility, as they are often capable of firing .45 Colt rounds, allowing for different levels of use depending on the application. Conclusion
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.
