These STL files are used to print the parts for a single hybrid bicycle model. When finished the bicycle is 11.5" long and about 7" high. Some additional parts and hardware are necessary for assembly. i.e. the wheel spokes are made from straightened paper clips and two of the frame members are cut from carbon fiber archery arrows. A few 2 - 56 bolts or sections of 2 - 56 threaded rod and some 2 - 56 nuts or lock nuts are needed. A printing and assembly document will be included also.
