I wanted a way to prevent the silica gel from touching my filaments. So I designed this tray to lay at the bottom of my Dry box.
Why don't I want my filaments touching the silica gel, you ask?
While pure (transparent) silica gel is totally safe to manipulate, some types have a moisture indicator, such as cobalt II in its composition. And it is not safe to touch it and touch your eyes or mouth. So, wear gloves or simply avoid touching it.
