About the project
Job Title: 3D CAD Designer Needed for Simple, Low-Cost Plastic Medical Device Prototyping (Dental) Job Description: I am looking for an experienced CAD designer to create a 3D model (.STL and .STEP files) for a simple, single-piece disposable plastic cap that snaps onto standard dental mouth mirrors. This is a low-budget project aimed at creating an initial prototype. The design must be incredibly clean and optimized for high-volume, low-cost injection molding (no complex side-actions or undercuts in the mold). Product Specifications: • Function: A thin, optically clear plastic shield that snaps over a standard dental mirror to protect it and manage water/fog. • Dimensions: I need two variations of the same design to fit standard dental mirror sizes: 1. Size #4 (22mm outer diameter) 2. Size #5 (24mm outer diameter) • Key Features to Model: 1. Cantilevered Snap Rim: A small, flexible plastic lip around the edge that deflects and snaps firmly onto the metal backing of the mirror. 2. Ejection Tab: A tiny thumb-notch or tab on the back edge so the user can easily pop the cap off. 3. Micro-Spacers: 3 to 4 microscopic internal bumps (approx. 0.05mm high) on the inside rim to prevent a vacuum seal against the mirror face. 4. Flat Optical Window: The front face must be perfectly flat with no mold gates or extrusion artifacts in the center line of sight. Deliverables: • 3D CAD files in .STEP format (for manufacturing) • .STL files (ready for 3D printing) To Apply: Please reply with a brief mention of your experience designing parts for injection molding or plastic enclosures. Let me know your estimated turnaround time and fixed price for this project.
