The cut off score for NID M.Des (Product Design) prelims varies every year. It depends on the number of students taking the test, difficulty level of the exam and the reservation quota applicable to the students. Hence, the score cannot be predicted each year.
However, from past performance of students, a score of 70+ will be a safe score to target.
