Nice job!

The biggest thing that stands out to me is the shield doesn't seem particularly useful, necessary nor easy to make. Having a large slot for the chain leaves a lot of room for material to be sucked into the gearbox and once debris in there, a shield can actually speed up the wear of the gears; this is why 192 makes their drivetrain almost 100% sealed (and maybe 100% this year). Additionally, if you look at 254 they do not use shields on their gearboxes and have (obviously) had a lot of success. I would consider reevaluating your use of one here.

(One last thought: machining holes in your plates to mount the shield will be more difficult than it was on 192's 2014 gearbox as your plates curve out)

Anyways good job, I'm curious to see how the 5mm GT2 belts do!
