Photoreal 3D Assembly Renderings

I need six small mechanical assemblies modelled in CAD and rendered as
a single six-panel figure for a peer-reviewed robotics journal article.

Each panel shows a parallel-jaw robotic gripper engaging a different
workpiece held in a fixture: a threaded fastener, a circuit board in an
edge connector, a snap-fit enclosure, a crank on a shaft, a pouch cell
in a recess, and a two-shell enclosure being pried apart..

I will supply a reference mockup showing exactly the layout, camera
angle, lighting and annotation style I want, plus a document giving
every dimension. The dimensions are taken from a physics simulation and
must be followed exactly rather than replaced with standard hardware
sizes.

What matters most is consistency across the six panels: identical
camera position, identical background, identical gripper model. Clean
and consistent is better than photorealistic. The reference style is
the task-montage figures in robotics benchmark papers, not product
photography.

Deliverables
Six rendered images, consistent camera and lighting
One assembled 2x3 montage
STEP files for every model
Native CAD source files
The render scene or project file
A note stating which software was used

Requirements
Mechanical CAD experience, SolidWorks or Fusion 360 or equivalent
Ability to model a correct helical thread at a specified pitch
Rendering capability, KeyShot or the CAD package's own renderer
Willingness to be named in the acknowledgements
Not required: robotics knowledge, simulation, or programming.
Everything needed is in the supplied documents.
Please include in your proposal:
Two or three examples of mechanical assembly renders you have made
Which software you would use
Confirmation that you can match a supplied reference layout exactly
