@BrookeStephen - It looks very good. If I may make a suggestion, the top of the power unit is more open. You can see light spilling in from the top in the screen shots for "The Enemy Within". Are you making your plans based on FJ's blueprints?
I've used FJ's blueprints for the ship, but small components such as this unit aren't pictured in detail. Yes, I know about the top being open - saw in "Court Martial" episode, just how they can be lit from above. I pulled many stills off the episodes and found one pic of the desktop model of the original TV soundstage, where the top of this unit is visible - seems to be the right shape - maybe the hole at the top is alittle smaller than it should be... can you find the desktop model of the soundstage and tell me what you think?
Thanks in advance!
Are you referring to the one that was used for blocking shots and planning?
It's a start, but as with paper models they might not be accurate on all the details, including the opening of those power units.
In "The Naked Time" you can see pretty clearly how far it is open by where the light is spilling in and the softly lit interior of the power unit.
But, I've also seen the interior top completely dark in "The Enemy Within" on one of the units either due to lack of overhead lighting or a covered top so you could say that top piece might be retractable
Or split the difference and have one of the two units open top and the other closed
