Update (1/21/23): A common complaint for the BOB57 is the lack of a heat sink and overheating, and while I haven't had that problem, I am sure it's a higher likelihood once the weather warms up. So, I have modified covers with air scoops and exhausts. This will allow for better cooling from external fan air, prop-generated airflow, or forward motion from the drone while limiting water and other matter from entering.

2RAW posted their BOB57 side plates/cover on their Thingiverse, but they did not match the one I had. On the last standoff, 2RAW's side covers were too tall and started higher than the covers I have. So I made some small tweaks to them, and now I can print them in whatever color I want. Thank you to the folks at 2RAW for giving us access to the STL files for their amazing quads.
