4pcs Mavic Air 2 Dustproof Charging Port Protector Cover for DJI Air 2S / Mavic Air 2 Frame and Battery (1 for Frame,3 for Battery) 3D Printed

Does what it describes.

Very tight tolerance it does fit just takes a little more effort to get it off. Once you get it on I suggest doing it evenly and press on not too hard. This is not the rubber soft cover that you’re expecting. It does fit.

While I appreciate the technology behind printing plastic components, these have not been designed with the inherent tolerance omission on fit. I carry blue painters tape to secure the caps when traveling. (btw - if you're buying these to cover the batteries on a plane, they do not require the terminals to be covered)

Two out of three of the battery protectors fit. You can tell they were 3D printed. Not a bad idea just not a consistent size/fit.

Out of the 4 received, 3 work and are snug against the battery pins. 1 of the covers is too small to fit over the pins (see picture). The bottom cover is the correct size and you can see the opening size. The top cover is the one that didn’t work and was too small to fit over the pins.

The dust protectors do not stay in or fit well. They're cheap and poorly made even for a 3D printed option. You can buy this product for a fraction of the price on Ali Express - so look there rather than here. At least you'll waste less money doing so.

These are nicely made, but the don’t fit the battery contacts very well. They fall off in my fly more combo bag. All have to doIs just lightly touch like while getting out the MA2 and they fall into the bag. These need to be made so they kinda snap in place. In my opinion. They are better than nothing so I’m going to keep them.
