Somehow I seem to have lost the original lens cover for the M3.  I may of lost it when swapping out for an ND filter.  I cant seem where you can purchase one on the website?

I don't think you can. Get a UV filter. It will be even better.

You may try check our DJI Where To Buy platform on this link ( https://www.dji.com/where-to-buy ) to see if the DJI Mavic 3 Original Lens Cover that you need is available. In addition I hope that you can get some recommendations from our DJI Co pilots with regards to this inquiry. Thank you.
