Print with 2 to 3 shells and zero infill. This is not a requirement but just general advice - it worked well for my print but YMMV. Take a picture and post in the RepRap forum thread if you would like to participate in the competition. Prize is bragging rights and the choice of competition piece for the following weeks.
