Mechanical engineer — benchtop oboe reed profiling/scraping machine (STEP + workshop drawings)

We need a mechanical / industrial design engineer to turn an existing concept into a fabrication-ready package for a small benchtop machine that profiles/scrapes oboe reeds (Arundo donax) on a tied blank (plaque + mandrel + interchangeable cam template + guided carriage + adjustable blade). Deliverables: - Solid CAD (STEP preferred) of assembly and parts - Dimensioned workshop drawings (PDF) - BOM with materials and critical tolerances - Short manufacturing/assembly notes We already have a conceptual package (OpenSCAD/STL + first STEP draft). Improve it to shop-ready quality; do not copy commercial products.
