Want to design your own 3D models but don’t know where to start?
This 30-day CAD learning plan is built for absolute beginners who want to design STLs for printing — without paying for expensive software or coaching.
Whether you’re a student, hobbyist, or future freelancer, here’s a simple roadmap using free tools like Tinkercad and Fusion 360.
📅 Week 1: Basics with Tinkercad
🔗 Tool: www.tinkercad.com
📌 Focus:
- Understanding 3D space (X, Y, Z)
- Using basic shapes (cube, cylinder, hole)
- Creating keychains, text plates, phone stands
🎯 Goal: Complete 5 beginner designs and export STL files
📅 Week 2: Slicing + First Print Designs
🔗 Tool: Ultimaker Cura
📌 Focus:
- Import STL and slice
- Infill, supports, layer height, preview
- Calibrate print settings using your designs
🎯 Goal: Slice and print 3 of your Tinkercad models
📅 Week 3: Start Fusion 360 (Free for Personal Use)
🔗 Tool: Fusion 360 Personal License
📌 Focus:
- Sketch, Extrude, Fillet, Chamfer
- Create dimensionally accurate models
- Parametric modeling (change sizes anytime)
- Beginner designs: pen stand, box with lid, mobile holder
🎯 Goal: Create and export 3 working STLs
📅 Week 4: Real-World Design Challenges
🧠 Practice Projects:
- Design a wall hook with screw holes
- Build a simple clamp or hinge
- Create a tray that fits your 3D tools
🎯 Goal: Model + print 2 working functional items
🧠 Bonus: Blender for Artistic Modeling
If you want to sculpt organic shapes (like figurines or jewelry), explore Blender:
- Free and open source
- Great for artists, sculptors, cosplayers
- Use “Sculpt Mode” and modifiers
