Rear Chain Guard Re-Design

I changed the design of the rear sprocket guards and 3D printed them.

The front half-circular guard section required no changes since I can insert and remove it easily by turning it 90 degrees, sliding it between the top and bottom frames, flexing the tabs on the ends open to slide it over the frames, unflexing to close the tabs and inserting M3 screws or pins to hold it tight against the frame.

I re-designed the single back elongated guard to be 2 pieces that could be separately slid in place from the top and bottom, thereby avoiding inference with the wheel hub, square encoder end cap and circular motor housing. Top, bottom and side M3 screw connectors on the guards hold the 3 guard pieces together.

The above picture shows the opposite side of the guards and frames facing the inside of the AGV. It shows the semicircular cutouts for the cylindrical motor housing.
