Reviewing Your Design

Review your work from every angle before asking for a print. Use this page for self-review and peer feedback.

Printability checklist

• A broad, stable face is oriented on the workplane.
• There are no floating parts or accidental gaps.
• Connections, walls, rings, pins, and small details are thick enough to survive use.
• Overhangs and bridges are short, supported, reoriented, or redesigned.
• Holes and fitted parts include reasonable clearance.
• The scale and measurements suit the intended user and purpose.
• The design avoids unnecessary supports, material, and print time.
• The model is original, appropriate, and complete.

Review the examples on 3D Printing Principles and Rules if you are unsure.

Peer feedback protocol

Work with someone who has not been staring at your design all class.

1. Rotate the model through the top, front, side, and underside views.
2. Explain the user, purpose, and two most important success criteria.
3. The reviewer identifies:
   • one effective choice;
   • one printability risk;
   • one specific suggestion or question.
4. Record the reviewer’s name and exact feedback in Notion.
5. Decide what you will change. If you reject advice, explain your evidence respectfully.

Remember

Useful feedback is kind, specific, and helpful. “It looks good” is kind, but it does not help the designer make a decision.

Create a fly-through

Record your screen while rotating the design in all three dimensions. Show the underside and any openings—not only the most flattering view. Submit this with the model so the print can be checked efficiently.
