🧠 About This Video
Designing precise, functional parts for 3D printing in Blender is far easier than most people realize—once you understand the correct workflow.
In this video, I walk you through:
• Setting up Blender properly for precision modeling
• Using Blender’s grid, units, and orthographic views correctly
• Designing a dimensionally accurate headphone mount from scratch
• Creating clean geometry using non-destructive techniques
• Preparing and exporting a model correctly for 3D printing
This workflow is simple, repeatable, and practical—whether you’re new to Blender or coming from CAD software.
