Notes
- Exact nominal dimensions. Arduino UNO shield outline 68.58 × 53.34 × 1.6 mm with the UNO's two 2.54 × 2.54 chamfers on the +X edge; datum is the board centre, bottom on z=0.
- Three mounting holes Ø3.2 at (−19.05, +24.13), (+31.75, +8.89) and (−20.32, −24.13), i.e. UNO holes (15.24, 50.80), (66.04, 35.56) and (13.97, 2.54) from the UNO's lower-left corner. The fourth UNO hole is not drilled.
- Tallest parts: three Ø5.0 electrolytic capacitors, top 7.0 mm above the board bottom, at (+14.10, −4.95), (−20.57, −11.30) and (−26.92, +15.37).
- Not modelled: Arduino stacking headers, 3.5 mm terminal blocks and servo headers (all ship loose), ICs and small parts.

Questions
How big is the Adafruit Motor Shield V2?
68.58 × 53.34 mm (2.7 × 2.1 in), the Arduino UNO outline, 1.6 mm PCB; 7.0 mm tall at the capacitors without headers.
Which mounting holes does the shield have?
Three Ø3.2 holes on Arduino UNO positions (13.97, 2.54), (15.24, 50.80) and (66.04, 35.56); the hole at (66.04, 7.62) is not drilled.
Does it fit an Arduino Uno enclosure?
Yes: same outline and hole positions as the UNO; allow for the stacking headers and the terminal blocks above the board.
