If you are reverse engineering something like those used sleds, it’s unlikely you are going to have any kind of paper to give you those critical dimensions. As he said, those sleds were bought second hand. You ain’t ever going to get any kind of manual with them.
As far as measuring goes, It’s all G20/G21. I’m pretty sure the overwhelming vast majority of 3D printing people own a 6"/150mm digital caliper. Metric or US Customary numbers are available at a mere push of a button. And you should also own a 6"/150mm stainless steel scale. Evem Mitutoyo are less than $20. Though I prefer Shinwa brand myself because I find them easier to read with my old feeble eyes. Buy one or several. But to be honest, just about everything in the US these days is metric. We just don’t brag about it.
Those are the 2 basic tools you need at your desk when you are reverse engineering a part or design something the new the world has never seen. Add a pencil and a sketch pad and you are set.
The sleds might not have a dimensional drawing, but the drives that go in them with all their screw holes would. There might even be an existing 3d model of a drive that they could have used to check interference of their design against in fusion.
