Designs are created so you’re able to assortment +/- step three.0 S.D. around the for each dimensions (find Fig step one ). That it lead to length ranging cuatro.0 inches to eight.5 in (ten.2 cm to 21.6 cm), and you may width (circumference) anywhere between 2.5 inches so you can seven.0 in (six.cuatro cm to 17.seven cm), playing with 0.5-inch (step one.step 3 cm) increments (come across Fig step one ). That it produced an excellent 10 X ten matrix off 100 you’ll systems. However, instance a big selection set you can expect to xcheaters overwhelm people. We chose to shot step 1/step 3 associated with the space, producing 33 activities across the listing of room.

Patterns have been light-weight, strong synthetic which have a softer surface (look for Fig 1 ). Once printing, patterns was basically appeared by the computing recording to make certain precision of length and you can width. None expected reprinting getting reliability.
