Ok, it's not modelwork but thought some of the 3D rendering blokes here might find this of interest. Rendering below is my proposed design for the Koenigsegg
(Swedish super car) Hood Release. Koenigsegg recently held a competition for the design of this component. Unfortunately I didn't become aware of it until after the deadline, but decided to go ahead and prepare a design anyway... a good exercise.
The housing is carbon fibre, the handle (design derived from an element in the Koenigsegg logo) is machined titanium. The handle is attached to a grooved cam on the back side of the housing. When the handle is turned counter-clockwise, it pulls a spring-loaded cable that releases the hood latch. The cable passes through the guide just visible behind the right edge of the housing.
Components were drawn in Autodesk Inventor Pro 2012 and rendered in Keyshot 2.
