Yes, seeing them together does really point out the vertical stretch.
I'm sure I could fix it as the width and height pixel counts are hard coded in the embedding HTML. But that's for the "view" I "printed". So if I change the pixel counts and then change the view it'll be wonky a different way. So, the best way appears to be to just insert the image the standard way.
What it doesn't say is that the thickness of the dividers is usually 1/4". But, that would get busy in the drawing. And, the fabricator can use whatever thickness they want. For instance, if you used steel 1/4" would be waaaaaay too heavy, while in wood 1/4" might not be enough.
Using the dimensions found in this thread and this site, this weekend, I built this from ⅝ plywood and stained with tung oil. I secured it with the bolts that I believe are used to secure baby seats.
I'll add a few more to my "Coming Out of Retirement" thread. Thank you for the guidance!
