This recovery float is intended for easy recovery after a fall into the water.
The Mavic Mini will be irreparably damaged, but whoever is covered by disaster insurance will be able (maybe) to return it to receive the replacement.
It is therefore suitable for those who takes off into the open sea from a boat.
It must be aware that this addition exceeds the limit of 250 grams, so in many countries the drone must be registered.

170 grams of positive thrust in fresh water should ensure its floating, but it is my assessment that could be wrong. For obvious reasons, I cannot perform a real test. I therefore do not take responsibility and if you decide to use it for a recovery after a fall in the water, you do it under your responsibility knowing that floating is not guaranteed.

The buoy is conveniently fixed with two zip ties, but to further reduce weight, it would be better to use a technical lacing tape, of the type used in the aerospace industry. This is what I often use instead of zip ties: http://www.breydenproducts.com/products/aerospace/polyester-tape-a-a-52081

Materials and methods

The best material to make this print is polypropylene, for its very low density (0.9) and for the excellent interlayer adhesion, which make it definitely waterproof.
With rectilinear infill at 5% and two perimeters the weight should be around 31 grams. Its volume is around 0.2 liters, the result is a positive boost in fresh water of about 170 grams.
There is an even lighter material, the FormFutura Pegasus Ultra Light PP filament, density 0.75, with which you can go down to 23 grams. Because this material is softer, I advice to increase to 3 perimeters the compression area subject by zip ties.
