## Summary
Prusa Research has published a new Prusa Academy course titled "Beginner's Guide to Blender for 3D Printing: Edit and Remix STLs." The course targets users intimidated by Blender's complex interface, focusing narrowly on practical STL editing skills including direct mesh editing, sculpting, and modifiers. Prusa also released a companion blog post demonstrating a five-minute STL editing workflow using a sample vase model from Printables. The course format combines structured text, short videos, quizzes, and completion certificates.

## What the course covers
- Course focuses on editing existing STL models from repositories like Printables, not creating models from scratch
- Covers direct mesh editing, sculpting, and modifier workflows
- Uses Blender's Edit mode and Proportional editing for shape modifications
- Includes practical techniques like axis-constrained scaling (Shift+Z to lock Z-axis)
- Course materials use short 5-20 second videos per step rather than long-form video tutorials
- Blender runs on Windows, Mac, and Linux
