Abstract: A system includes a first plate and a second plate disposed in parallel, and guides disposed between the first and second plates, including a first guide cantilevered from the first plate and a second guide cantilevered from the second plate. The first guide is offset from the second guide, and a plurality of bearings include a first bearing disposed at a distal end of the first guide, and a second bearing disposed at a distal end of the second guide. The first guide is arranged to mate with the second bearing, and the second guide is arranged to mate with the first bearing. The system further includes elastic members, including a first elastic member between the first plate and the second plate and provided concentrically around the first guide to extend in an axial direction along the first guide.
