Bottom Cover for F330 Drone Frame

thingiverse

This is a bottom cover, cap or lid for the F330 drone frame. I decided to flip the lower plate of the frame to get enough room for the battery. This way, the power distribution solder pads are on the outside/bottom. To protect them, I designed this simple cover. I also left enough space for placing a power module inside. The cover fits inside the four rounded, rectangular holes of the board to hold itself in place. There is a counterpart of which two are needed to screw the cover down. Inside these upper parts are holes to allow for passing through of smaller cables and connectors (like the power/sensor connector for the APM/Pixhawk). The upper side is designed to be as small as possible and save as much room as possible on the top side of the board (in my case: for the battery). You will need four countersunk M3 screws, at least 12 mm long and matching nuts. There are recesses for the nuts.
