The starting vectors were done in Illustrator. I spent about fifteen minutes creating the starting file I wanted. The vectors were then imported to to be modified and then to create a routing file.
I separated the spokes of the wheel and then used the jigsaw tool (on each segment) to pull out the center.
I then used the point edit tool to round out the ends. This would make the spoked round – without any bulges or sharp edges.
After re-centering the spokes I added the axle hole and wheel ring. Borders and an outline were also added to the letters.
