I am an engineer and manufacturer. I have built many gearboxes for electric skateboards (ESK8) in my own design and architecture. I have decent knowledge of aluminium processing technology, since I have been working for more than 5 years. I also work with Autodesk Fusion, I can design and manufacture parts according to specifications or drawings. I could help with professionals and design and hobby orders. I also have a CNC machine, and I can process parts for individual orders.
Feel free to contact me if you have any questions.
