'''2017-06-12 Update''': those two side plastic parts that come with the middle frame aren't the same pieces. I'm still trying to track them down.

Figured it out as I was typing out the question.
These side plastic parts are part of the middle frame, which you can buy on ebay by searching "dji mavic pro middle frame". I found a middle frame with two side supports for $15.
I imagine it would be easy to 3D print this part - it's just a flat piece of plastic with a hole in the middle.
