Use to lift the frame 35mm out of grass. I use these on a Rotor Riot CL1 frame. These are a modification of my 10mm versions.
Printing: I printed this in PLA, and it worked well. No supports or rafts are necessary. I would recommend 3 or 4+ perimeters, top and bottom layers for durability. Infill should not make too much of a difference, but I used 20%. I have only every broken 2 on a hard, flipping fall, with 3 perimeters.
I attached the Fusion 360 .f3d file if you would like to modify.
