Successful student example for Measure for a User

Success example · inspiration, not a design to copy

Look closely. What makes this successful?

Real measurements and a size-check model help the part fit its intended object.

What to do

  1. Understand. Read the challenge. Circle the important need, rule, or safety limit.
