Guessing about 12½" tall.
in my current model the tallest length is 31cm (12.2") so thats very close. just the black bar itself is about 27cm or 10.5"
Guessing about 12½" tall.
Looking great! Closer indeed.
Though we have no better view of the left side, I think the surfaces may be angled back further than you have currently.

I noticed the brighter values as well and was trying to figure out why that is, but there is a problem. In order for such a tall plane to be just as steep if not steeper than the blue plane they would need to be tilted all the way back past the thickness of the panel or at least past the current back layer

also in the behind the scenes screenshots we have you can see that the top edge of the left side looks to be the same thickness as the middle area of the right side which is where i currently have it:

the only other way it could be tilted back that steep is if the flat areas of the triangles were significantly taller than what we currently have, which is possible (just look what happened with the vertical bar lol) but i would still be hesitant to say they are taller than the higher planes of the right side panel. If they were that much taller i would think they would be casting longer shadows on the bottom as well, but the shadows under the left side are actually shorter than the shadows on the right
It is still very weird though, maybe just something with the paint job and the lighting arrangement makes those areas look brighter?
Relooking at those lens panels, I noticed that the top one is not flush with the base.
I think we should reconsider the left side's construction and geometry. They may indeed be thicker then we originally assumed. It could still give us the edge thickness we see in that side view.
It is a pleasure dissecting/exploring this with you, mrcarkeys42 (and everyone else here too). Would you mind posting wireframes of the top and side views of your current model? I want to be able to see though it, without perspective distortions.

also i am beginning to come around to the idea of it overhanging,...
Hey guys sorry for such a long hiatus, just been busy with school is all and was maybe hoping for some more images to surface haha
Rest assured, ill be back with updates soon!
Another problem this creates though is the size of the linear rails. User Karstein messaged me and gave me the idea of using the railing to scale the rest of the piece. However most linear rails I have seen online would be too large for what the previously established scale would indicate. He had tried scaling a model to a 12mm wide rail (8mm thick) which is fairly common. scaling the rest of it to that railing size would make the back panel 18cm tall, even taller than what i had originally had. If the scale of my previous model were correct, the railing would be 5mm thick which is already smaller than i am able to find online. If my hand scale estimate were correct that would make the railing even smaller, so i honestly am just not sure at this point lol
EDIT: 9cm, not 6cm my bad
I still think the badge is a better object to measure from. Hands very in size, and it is an oblique angle.
https://www.mcmaster.com/#linear-motion-carriages/ and then "Ball Bearing Carriages and Guide Rails" and you should get a list on the left of various sizes, 5mm (and smaller) is available. McMaster have 3D models available so you can grab them and scale your reference image, (in Fusion 360 you can do this using the Calibrate Canvas option).
On a rough attempt to scale the flattest reference image
5mm rail gives a derived height of 70mm ish (Based on a 3.7mm height spec)
7mm rail gives a derived height of 105mm ish (Based on a 5mm height spec) <--- this is your guy- I''d guess a 120cm rail
10mm isn't worth trying because if you look at the aspect ratio of width:height its visibly wrong.
Edit: Does this help?

Another edit: I extrapolated a little more based on the assumed dimensions of a 7mm rail and came up with this:

I think there is some perspective distortion in the head-on reference image. Although the top left corner looks like its overhanging I'm not convinced it actually does - you'd think you'd see some indication in the pictures lunadude posted.
Luckily, other retailers are availablealso the print looks great! that looks very close in size, so i think i am in agreement that the 7mm railing is the one (though i probably will not be purchasing them since 100 dollars is a bit much for me, ill print the railings for mine)
