Quadcopter propeller guard (oval)

thingiverse

I bumped into some issues with circular prop guards on my ladybird v939 - they just wouldn't work properly! Each time I bumped something, they would compress a bit and impact the props badly. But these oval guards have some extra room to compress before hitting the props, and they hug the body of my v939 tightly, so even slight nudges won't unalign them. If you want to use these oval guards and still keep your copter's body shell on, you'll need to enlarge the arm holes in the shell a bit. The design I used was printed with 0.3mm layers and 100% infill, supports were added but no raft.
