There is a guy in the comments on this article pitching his adapter for a rear kickstand:

I’m a massive kickstand fan. Craig, a Surly and kickstand fan, designed two 3D printed stainless steel parts (part 1 + part 2) that will mount a KSA-18 kickstand onto Surly Troll, Ogre or ECR dropouts. Read more about kickstands HERE.

I tried ordering them from him but no success. It takes a few weeks to get them. The cost is a bit extreme for my taste compared to the actual cost of the kickstand. I tried placing an order and couldn't get it to go through in the end. So I am not sure what is up, but this is a solution also. Hopefully the guy makes it easier to get your hands on the product or releases the 3D prints to have them submit and printed for ourselves eventually.
