Assignment 2: Make something with as many materials as possible

For this assignment, I decided to make a model land-based sailboat.  The sailboat consists of a number of materials: 1) various types of acrylic, 2) abs plastic, 3) aluminum, 4) mylar, 5) thread, and 6) rubber.  All the pieces are made to tight tolerances so I could simply put all the pieces together without any type of fasteners or adhesive.  I used the laser cutter to create most of the pieces of the sailboat, with the exception of the aluminum mast and wheel axle rods, which I cut with the waterjet cutter.  Here is a picture of the unassembled parts:

The wheels were attached to the axles by carefully engineering the tolerances of the rod holes.  The axles were then attached to the body of the sailboat with acrylic holders that were press fitted into holes cut out into the body.  The mast was also attached via a hole in the body.  Here is a picture of the underside of the sailboat:

I cut out square holes in the mast so I could put in acrylic pegs to hold the sail frame.  The sail frame also had holes drilled in key points so I could thread the mylar sail to the frame.  Here are a couple of shots of the final piece:
