Using a caliper
The most common technique for taking accurate measurements is the use of a tool
called a caliper, a must have for anyone who models for 3D printing. Calipers
measure distance with a high degree of precision and can measure in three different
ways; the outside diameter of an object with the outside jaws, the internal diameter
with the inside jaws, or the depth with the depth probe at the far end. The easiest
kind of caliper to use is the digital type.
Simply turn on the digital caliper, tare or zero the reading while closed, then open
the jaws, put the object to be measured between them, clamp it down, and take the
reading. It's fast and relatively accurate without much effort. Most models even
have a port that can transfer the measurements directly to the computer. But digital
calipers have the disadvantage of being more expensive and relying on batteries
which when run out eliminate the ability to measure accurately.
If budget is a concern then perhaps a Vernier caliper is preferable. These calipers
operate purely mechanically, but have a clever trick that allows them to be just as
accurate if read properly.
