Hi Mate Hannes E.,
I have read your proposal downgrade MacOS Big Sure to Sierra from a mac mini computer and I know I can help you because I have experience in mechanical design and 3D modeling in Autodesk Inventor and Fusion 360, I have made several designs for the industry both artistic and mechanical.
I have also programmed CNC machining and cutting using G-code, 3D printing for STL models and welding, the latter being automated using a robotic arm.
I have experience using Mechanica Static Simulation (FEA), ideal for analyzing designs.
I would like to work with you, I have extensive experience in product design and I know the different manufacturing processes, I invite you to visit my profile where you can see some of the projects where I have worked.
Do not hesitate to contact me, I'm always at your service waiting for your proposal.
