It fit in the quad-copter I have. I can fly it in living room now, and don't need to worry that it will get damaged by hitting the wall. I improved the design after the one shown in picture. That one have some vertical beams broken right out of print, because of weak structure and our printer axis got loose. So in the file uploaded here, I increase the thickness of vertical beams. Also there is cut open to help it snap on easily. 0.1mm layer height with 89% infill, PLA, bed temperature 60C with glue on Kapton tape.
