Mechanical CAD Designer for Plastic Cap

I'm looking for an experienced mechanical CAD designer to make a simple modification to an existing plastic cap design. Project I already have the existing CAD model. I need one feature of the cap modified while maintaining proper fit and manufacturability. This is not a new product design—it's a straightforward revision to an existing part. Requirements Experience designing injection-molded plastic parts Strong mechanical CAD skills (SolidWorks, Fusion 360, Creo, or similar) Ability to work with STEP files and provide editable source files Understanding of wall thickness, draft angles, tolerances, and manufacturability Deliverables Updated CAD model STEP file Native CAD file Brief summary of the changes made Please include in your proposal Which CAD software you use Examples of similar plastic part or product design work Your estimated time to complete the modification Your fixed-price quote This is a small project, but if everything goes well, I have additional product development work available in the future.
