Quadcopter Propeller Gaurd

thingiverse

I upgraded my quad-copter design after noticing a major flaw in the original model shown in the picture. Those vertical beams snapped right off during printing due to a weak structure and our printer's loose axis, which was a huge setback. So, I made some key changes: I increased the thickness of those vertical beams to make them more robust, and also added a cutout to make assembly much easier. Now my quad-copter fits snugly in my living room and can even fly around without worrying about it crashing into walls.
