Rotation of the drive screw can affect translation of the carriage, such that the position of the carriage is adjustable along the length of the drive screw. Moreover, the carriage can include a spring, which can be attached to the extendable cover via a pivot arm. The cover can be wound onto a roller and, when a length of the cover is unwound from the roller, the spring can pivot the arm to pull the cover into an extended configuration.
