Halo Doc Product Design Refinement

I have an existing STEP file and working prototype for a wall-mounted dental product called Halo Doc. The product is functional and approaching market readiness. I am seeking an experienced product design engineer to optimize the existing design for manufacturing. The product was originally designed for FDM 3D printing and I recently received an unexpectedly high HP Multi Jet Fusion (MJF) quote. I need an engineer who can evaluate the design, reduce material volume and manufacturing cost, optimize it for MJF production, and prepare it for future urethane casting and injection molding while maintaining its premium appearance and functionality. Existing STEP files are available. Experience with MJF, injection molding, DFM, and consumer or medical products is strongly preferred.
