\caption[Helically coiling fibers inside the axis tube]{
The necessary mesh spacing can be reduced by coiling the fibers inside of the axis tube. The coiled fibers enter
the inter-mesh space at an angle equal to the helix lead angle, which reduces the amount of space necessary to
complete the transition to horizontal along a circular arc. In this example, a \qty{6}{\milli\meter} outer
diameter tube with a \qty{0.5}{\milli\meter} wall thickness is shown with 6 fibers with \qty{0.9}{\milli\meter}
outer diameter coiled to a constant bend radius of \qty{9}{\milli\meter}. The lead angle of the resulting helix
is \qty{61.5}{\degree}, and past the tube exit, only \qty{5.16}{\milli\meter} of inter-mesh space are necessary.
