machined aluminum parts

Description:Aide

Hello,

I would like to machine two copies of this aluminum piece.

I took care to attach to my request two renderings to get a glimpse of what I want to finish.

the file is in .STEP.

I wish a beautiful finish (polishing) for each of the two parts.

if possible before validating the manufacturing process with a machinist, I would like to be able to ask some questions when to the feasible side of some details of this piece (and avoid mistakes!).

note: I am from France.

thank you!
