The gears meshed perfectly. However, the design turned out to be too thin, and caused pieces to be unintentionally cut off by the laser cutter as shown in fig 4a. This could also be due to board I was using, though I decided to increase the weight of the lines. After thickening the thin spots, pieces still crumbled away due to the laser, though the resulting design, as cut out in fig 4b, was sturdier and worked much better overall.
Is this a good/useful/informative piece of content to include in the project? Have your say!
