Video Guide

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.

Fast

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.

Free

Compatible

Papa’s Best STL thumbnail viewer displays countless STL variations, even where other programs fail:

Custom colors

a folder with thumbnails, their background purple and the objects mint green

Custom object color is ignored if the STL comes with embedded color information! Changes do not take effect on existing thumbnails until you clear the Windows thumbnail cache! This is a Windows limitation.

Dark background on some thumbnails

a folder with two thumbnails whose background is entirely black

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.
