These are front feet extensions and a rear foot for the DJI Mavic Pro. I saw designs similar to this and designed my own in Tinkercad. They will raise the camera (measured from the bottom of the lens) from 5/8" to 1 3/4"and the rear of the craft from 7/16" to 1 5/8".
I printed these with PLA, with 4 top and bottom layers and 4 outer shells.
You may need to adjust the scale slightly for a tight fit on the front extensions. I found that the higher resolution and infill I printed on the test prints the looser the fit. These files are a nice tight fit on my Mavic Pro, but results may vary depending on certain printers, settings, material used, etc.
