A file with .stl extension is a 3D graphic file native to Stereolithography technology. Stereolithography is basically a type of 3D printing technology to create 3D models.

And for that very reason, we take a look at a compilation of the most useful, interesting and fun 3D printing STL files for back-to-school 3D printing. From organizers, to pencil cases, rulers, paper ...

3D models can be created using any CAD application like CATIA V5, UGNX, SOLIDWORKS and so on. Once the models are ready, they can be converted to STL format for 3D Printing.

May 16, 2018 STL files are everywhere. When there’s something to 3D print, it’s probably going to be an STL. Which, as long as the model is good just as it is, is no trouble at all.

3D printing can be a fun and productive hobby and skill, but there can be a lot of confusion around the files involved. Here are some you should know about.
