About STLOrganizer
STLOrganizer is an independent project created by George-Adrian Balas, a 3D printing enthusiast who was tired of digging through messy folders of STL files. The goal is simple: make it easier to organize, preview, and manage your 3D printing library so you can spend less time searching and more time printing.
