Drone feet

These are drone feet. With rounded design i tried to make feet in a way, that they can slide on hard even surface. But its sliding properties is really determinated by material of your choice, you can probably make them grippy with some rubberlike materials.
They are meant for motor holes, measurements are taken from my drone frame holes.
It will take screws with additional 2mm (its the width that adds on motor mount holes)
In slicer settings you can add more top layers, to compensate for material that is grinded way from slides, if such will happen.
To save on weight, i suggest playing with infill to be less as possible. I printed on 15% you can even try on 0% infill, making it hollow, therefore lightweight as possible.
