Quadcopter Battery Roll Cage

I carefully crafted this design to snugly fit a Martian frame, effortlessly accommodating my 4S 1500mAh batteries without any hassle. Simply screwing on the top with the top plate mounting screws gets the job done, and while I haven't had the chance to test it with other frames, it's clear that this build is tailored to perfection for its intended purpose.
