thinking that it might be difficult to make by hand and cnc is the way to go to get a precise fit
wood selection would also be critical
anyone tried to make something by hand like this or at least without a cnc
shrinkage might be bad for the laptop
introducing some strain relief into the design would be needed
like a flexure
the other aspect is the laptop material
aluminum might be easier to get a nice fit where as plastic might be harder to get a good fit due to less stiffness
plastic might not hold up to the strains of the wood shrinking or expanding due to moisture
