As a way of giving back to the paper modeling community I uploaded the patterns and instructions to the download section. And just in time for Christmas. Have a nice holiday season everyone.

I just joined this forum due to this thread and Henry this is so amazing and intricate. I have only dabbled in 3D modelling a bit and process of making something really gives a new perspective and insight into subject.
That part is indeed bracket for placing Course Analog Sun Sensors(9 in total) CASS-42 and CASS-47. They were placed in such odd way to avoid proximity to medium gain antenna according to this paper on "Electromagnetic compatibility of MARS Orbiter Mission spacecraft"

Based on the Microwave Simulation in CST Software, it was analyzed that (Course Analog Sun Sensor) CASS -42 and CASS - 47 Subsystem would be experiencing high Electric Field (about 80 V/m) due to the proximity of the MGA, hence they were relocated.

Also a while ago I found this animated assembly of MOM and put it on Youtube might be of some use, it has all parts labelled.
Happy Holidays!
