# An adjustable spacer

## Abstract

An adjustable spacer (80) for adjusting the spacing between two bodies comprising: i) a first rotatable indexing mechanism (82), the first rotatable indexing mechanism (82) configured to rotate in a first rotational direction about a rotational axis; ii) a second rotatable indexing mechanism (84), the second rotatable indexing mechanism (84) configured to rotate in a second rotational direction about the rotational axis, the second rotational direction being opposite the first rotational direction; wherein the first and second rotatable indexing mechanisms (82, 84) are configured such that rotation of the first rotatable indexing mechanism (82) by a given angular rotation in the first rotational direction about the rotational axis changes the length of the adjustable spacer (80) along the rotational axis by a first length, and rotation of the second rotatable indexing mechanism (84) in the second direction by the same given angular rotation about the rotational axis changes the length of the adjustable spacer (80) along the rotational axis by a second length, the second length being the same or different to the first length.
