The Penholder

The first sub-assembly is the penholder. The penholder is the mechanism that grips the pen firmly
and allows it to move up off the paper and down onto the paper. You may have to adjust the pen-
holder to suit the pen you are using (you can add or remove plates to do this). Ideally, the pen
should be as close as possible to the center of the wheelbase. This allows the Turtle to turn while
the pen is down without making a mess.
