In the orbitalreflector.com website there is a picture of a ring that looks like it can deploy smallsats as part of a more complex launch. Reverse image search turns up another view, both shown below.
It reminds me a lot of SHERPA (What ever happened to SHERPA?) but is it an artist's conception, or a fairly accurate rendering of something that SpaceX will use to deploy small spacecraft?
