The first two photo taken are the most recent version of the Construction Servitor! The last three pics are before I added in the tube connecting its larger power claw to its power pack, and pipe connecting its head to the power pack.

I scaled the bits to be about the same size as a "Firstborn" Mk II Marine. Let me know if there are any issues with scaling so I can fix it!

Models are:
Prime Wolves by Tatsura
Mk2 Marine Squad by maz3r
