Part Dimensions
A size difference compares a printed part with its planned size. Negative means smaller than planned; positive means larger. Use the table for Questions 1–5.
| Part | Difference (mm) |
|---|---|
| Hinge | −0.45 |
| Clip | 0.2 |
| Wheel | −1/4 |
| Stand | 0 |
| Knob | −0.6 |
- A. −0.45 > −1/4; the hinge's size difference is greater.
- B. −0.45 < −1/4; the hinge's size difference is less.
- C. −0.45 = −1/4; the two size differences are equal.
- D. −0.45 > −1/4; the wheel's size difference is greater.
