Simple hook to mount the tool head cover out of your way when you need to swap nozzles or work on something underneath it. Its super simple and quick to print. Just press a magnet (4x2) in to the hole after printing, place it on the top rail and the magnet on the cover will snap right to it.
There is two print profiles, one for a thinner solid version and one with the Bambu Lab logo in if you like that kinda thing.
