I quickly found that my prototype was too thick for my liking. Unfortunately, I couldn't get back onto the printers to make another skeleton in time. Therefore, I tried to apply as little clay to the grip as possible, but this made it difficult to shape the handle appropriately. 

This caused the most trouble when carving the contour lines. These were mainly for aesthetic purposes, but the lines on the lower half of the flashlight were also intended to signify an area where the user was supposed to grip the flashlight. 

Since the layer of clay on the grip was very thin, these lines were unsightly. As a modification (and inspired by Chris D'Eramo's advice), instead of carving down into the clay, I decided to build these features out. I rolled out a few pieces of clay and laid them onto the grip so that my contour lines were now extruding from the surface.
