A quick search found several possible parts for WS2812. None seemed to be quite what you want, but I am not the one that wants the part, so I did not dig very deep.
Usually a direct product link would not be enough to be able to create a Fritzing part. In this case, the overview information includes mechanical dimensions, and even a PCP solder pad footprint. So if another part is really needed, there is enough information there (for one of the regulars here) to create it.
Thanks for your reply, Yes I did a search before posting and couldn’t find any that were the size of these. The most common package size is 5050 and I have that already, but I have yet to be able to find the WS2812 2020 variant anywhere
While I seem to remember someone making one of these a couple of years ago, I couldn’t find it, so I made a part (for me that was easier.) As always print out and check the footprint before ordering boards.
