Hi. I'm a professional freelancer, and I just completed a project (3D model, manufacturing drawings and laser cut files) for a machine composed of around 70 parts. That included sheet metal parts - sometime to be welded, sometime assembled using bolts-nuts - but also custom designed 3D printed parts and commercial products (also electronics ones) to be housed. My work is accurate and serious, and since you didn't mention to already have the final 3D model, I assume this has to be made. Creating the fulld cad model, and later prepare all the manufacturing drawings, requires more information to propose a realist offer, so - in case you would deem me as suitable - please consider the offer here (price and time) just a placeholder, and we can discuss deeply your needs, and what I can realistacally offer. I'm a regular business owner, so it's possible to send invoices. Cheers, Alessio
