Inspired by the joint that works the human jaw, this model was based on that joint's ability to first slide out of its resting position, (which allows the up and down motion), then rotate freely.

The lock position and six black dots have been geometrically designed to provide the operation code.

The user must locate the correct code or 'sweet' spot by placing the upper piece on the lower one (the clue is in the two sets of three black dots and the shape of the central lug) in order to ROTATE in an anti-clockwise direction to a closed or LOCKED position.

I have revisited the skills I learnt last year in DSDN 104 by designing my model first in Solidworks. Due to the initial intricacy of my design I was unable to finish it by hand so the most important decision I needed to make was when to redesign to suit my resources. I really wanted to create an aesthetically pleasing piece which I am proud to say I achieved.

Movements
Upper piece: Rotate/Pivot
Lower piece: Lock/Catch
Materials Used
Upper and lower wood shapes: bass wood;
Lock: aluminium wire, Sculpy and rubber (sandwiched between the circle and ‘D’ shaped Sculpy pieces);
Six black circles: inlaid Sculpy.
