Should really have probably got around to making some of these… before bashing the frame a few times
3D printed in solid PLA. Wasn’t sure if they would be deep / wide enough but they seem to be really effective. Even a slight brush against a wall or similar was enough to take it down without these so the difference is huge tbh. I haven’t clattered into anything full speed yet but these feel strong enough to take a significant impact, and will definitely protect the motors too. Total is 7g for all 4, v. happy with that and zero noticeable effect on flight characteristics.
Really nice simple design - will fit any 11xx size motors. Major kudos to Peter Provost on Thingiverse.
