Hello friends,
for the DSOC struts I tried two variants. 
First, I colored an Evergreen strip (0,5 mm x 0,75 mm) black using only a marker (below), but it looked too smooth to me, 

as one can see in the original image that the struts are also wrapped with blankets.

Therefore, I wrapped the Evergreen Strip with black masking tape (0,5 mm), which is much closer to the original and I like it better than the smooth black strip. 
Then I turned my attention to the two Star Trackers, which are parts of the Attitude Determination and Control System (ADCS) of the space probe on its approximately 2 billion-mile journey to the Psyche asteroid.
These are two ASTRO APS sensors from Jena-Optronik GmbH, which emerged in 1991/1992 from the former VEB Carl Zeiss Jena combine, a fact worth mentioning. 
Their dimensions I laboriously determined from this image.

For this I used two plates (5,5 mm x 5,5 mm) made of thin aluminum sheet (0,1 mm) with a central recess, standing slightly raised,
and two tiny cones, which I have to file from an Evergreen rod (Ø 2 mm x 2 mm). 
Since I cannot mount these delicate little parts directly onto the probe body, it is easier and safer if I contruct each one separately on a base plate made of black paper and then glue them completely onto the front (+X-Panel) to the right of the DSOC. 
I first carefully pre-drilled the middle recess with a 4 mm diameter drill bit, and then enlarged it with a mini square diamond file, which was a stressful task. 

Initially, I wanted to glue smaller spacers (0,5 mm) under the aluminum plates, but then I went about it differently, as one can see in the image that the white cones are sitting on a black base. 

And then I wanted to get even closer to the original and carefully cut out the tiny corners from the aluminum plates with nail scissors, which I had tried out beforehand on a dummy, as well as filing the round rod conically for the tracker cones. 

Then I glued short Evergreen strips (0,5 mm x 0,75 mm x 4 mm) around the recess as spacers using UHU CA,

and the aluminum plate prepared in this way was then glued to the base plate, which then resulted in the desired distance from the floor. 

Then I tried to cut off the 2,5 mm long cone, which wasn’t that easy.

I then wanted to glue a small black disc (Ø 2,5 mm) to the front of the cones. The problem is that these fiddly bits are so small and unwieldy that I had to invent this holder made of masking tape. 

Then I carefully placed this cone on the plate and was amazed at how well it corresponded to my imagination. 

The second aluminum plate was then scratched in the same way.


And now I just had to cleverly glue the two cones into the openings of the plates,

wherefore I fixed it between two steel rulers so that nothing could slip anymore.
Then I carefully dabbed UHU CA into the opening with an acupuncture needle, placed the cone at an angle, and adjusted it slightly. Afterwards, I dabbed the cone tip inside the opening with more drops of CA to further strengthen the bond. 

I then left both Star Trackers alone to set before I carefully placed them both on the probe to enjoy the great results. 

I will wait with the gluing until I have glued the still missing small details on the front and all around, including these Sun Sensors, which I will now tackle.

These are all just small details, but they are very time-consuming and require a lot of patience, from determining their dimensions to final scratch building.
