I took a few minutes and did some editing to your file. This is how I would approach the design. I cloned the board for the next layer presuming the boards are the same. I didn't finish the board sketch but it's close.

with as much accuracy as possible

You would need to give more info about what you want, FreeCAD can give you precision down to some fine detail like .000001mm for instance.

Accuracy is up to you and how good you are with a tape measure or calipers.

Here is an approach from another post:

liongate, I didn't have time to process your file but I made a sweep/morph, identifying the Map mode and Support might help you. I have been working on adding Morph to my Sweep macro which should make this easier to do. FreeCAD calls this "section transformation", I call it morphing. This ...

Since your new here I don't want to confuse things but I made a sweep macro a while back, it also has a learning curve so maybe something to use in your future here.

Here is how I would do it. Mapmode can be very helpful. You can map a datum line to the curve center, then map a datum plane to the datum line, then sketch on the datum plane that has an axis of the curve. Here is an example. There are some possibilities of TNP because of a mapped edge but this is p...

My suggestion : Find an instrument case, something that has a flat front and rear panel. You could go to a second-hand store and find something that's small enough to sit on your desk, tear it apart so you can measure it with calipers and a ruler. Start by making a hand drawing with key measurement...

Step by step please?

Sorry, I would but I'm out of time and I don't remember, I didn't know there was going to be a test . I think I moved sketch003 into the Body and copied the Body minus the Origin and pasted into a new doc, this gave me a new Origin.

Got to go, bye.

Here,it all looks OK and BOP OK. Copied the Body into a new doc and set a couple things. Weird issue, maybe has something to do with the Bend.
