New Prop Gaurd for my Hovership MHQ2 i loosely got the dimensions from the thing:586703 but ended up redesigning the entire thing from prop holes to splines and outer ring. I tapered the outer ring to try to reduce any blockage of the downwash from the props, i doubled the spokes to increase strength on impacts and reduced the size so that it can fit smaller 3D printer platforms like mine focusing the coverage from forward, angle and side impacts.
Printed in PLA they only last maybe two impacts but do very well dissipating energy on impacts, its usually enough to bounce the quad back from impact enough to reduce damage at the sacrafice of the gaurd itself.
Printed in ABS they did significantly better even surviving some crashes when i had receiver problems and it was dropping out of the air 50-100 feet like a brick.
it was designed for hovership but should fit any similar motor sizes with a 5 inch prop
