Print the small gears, winder, axles and spring at 100% infill, everything else at 50%. No supports or rafts required.

Make sure to check orientation to the print bed so parts will print properly without supports. The rear axle prints best laying flat down on the print bed.

All the parts should slip together freely, secure them with a small drop of super glue (some thought will be required here) 2 rubber bands will be required, one for each rear wheel for traction.
