Blender is not CAD software and it's very difficult to get precise dimensions.
I would suggest learning to use proper CAD software. you can get a free 'hobbyist' version of autodesk fusion 360 that's fairly cut down. (it lacks things like simulation and substantially more advanced features.)
other options include solvespace and freecad which are both FOSS- Free cad is powerful, but really difficult to learn- with OpenFOAM integration to solve simulations (like force loads, and such,)
OnShape shape is like a shitty version of F360, IMO, with the caveat that it's free version also publishes your models publicly for anyone to see and use.
Solid Edge is also comparable to F360 (though I haven't used it,) and it has a "community" version that's similar to F360's cut down version.
