Hola Gabriel
Not yet. And that's not an easy Feed. The problem is the isolation between 2,4 and 10 GHz, and also the different polarization V/H (NB/WB) for the 10 GHz Downlink. I know, there are several Ham's, who try to construct such a feed. There are several infos on the amsat-dl forum..
William Göldi, HB9PZK, is an engineer who build professional feed for ESA and others. He designed a feed for QO-100 and build now a prototype. More details on his webside. (In german, but you will see some great pictures, who give you an idea about the details) https://rfantennas.wordpress.com/

I am looking for a dual band dish feed for 10GHz/2.4GHZ to use for the Oscar 100 downlink/uplink.
What is your recommendation of either a commercial or a simple to build one?
