CAD Design Refinement for bathtub Water Filter

I already have a CAD design for a bath water filter product , and I need a skilled CAD designer to refine and adjust the model so it matches my updated requirements. The base design is complete, so this is not a full design from scratch — only edits and improvements are needed.

Your task will be to:

Adjust dimensions

Refine the proportions to look more polished, cute, and visually marketable.

Ensure the design is optimized for injection molding + silicone overmold manufacturing.

Deliver clean files suitable for both prototyping (STL) and manufacturing (STEP/IGES + 2D drawings).

Key Requirements:

Proficiency in CAD software (SolidWorks, Fusion 360, CATIA, etc.).

Experience with consumer product design (toys, bath products, or similar).

Understanding of DFM (Design for Manufacturing), especially injection molding and silicone overmolding.

Ability to refine a design for both aesthetic appeal (cute, kid-friendly look) and functional use (filter housing + strap + water inlets).

Good communication and ability to make it look really good while keeping functionality.

Deliverables:

Edited STEP and IGES files (for manufacturers).

STL file for prototyping.

2D drawings (PDF/DWG) with updated dimensions, tolerances, and assembly notes.

(Optional) A photo-realistic render for presentation.

I’ll provide:

Current CAD file.

Reference photos and diagrams of what I want.
