Summary
3D modeling and CAD unlock the full potential of your 3D printer—but only if you design with printing in mind. In this video, I share some essential tips and tricks for beginners to avoid common pitfalls and create parts that look better, fit better, and print stronger.
Here’s what you’ll learn:
- Wall thickness multiples → Always design walls as multiples of your nozzle size for smoother surfaces and cleaner fits.
- Fillet your corners → Rounded edges reduce lifting and make parts look more professional.
- Mouse ears → Add helper discs for better bed adhesion on tricky prints.
- Chamfer bases → Use chamfers instead of fillets on undersides for clean overhangs.
- Teardrop holes → Modify vertical holes into a teardrop shape to avoid sagging and messy fits.
- Print orientation → Design with layer lines in mind for maximum strength and durability.
These small design adjustments can make a huge difference in your 3D prints, taking them from frustrating failures to polished, functional parts.
