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.

I can model both the 22 mm (#4) and 24 mm (#5) caps, including the snap rim, rear ejection tab, 3-4 internal micro-spacers and the uninterrupted flat viewing window. The key DFM issue is reconciling snap retention with your requirement for a simple mold without side-actions; I would resolve the parting/ejection concept before detailing the rim. My background is mechanical product design and manufacturing, including enclosures and parametric CAD. I would deliver STEP and watertight STL files for both sizes, with one fit-review revision, for USD 275 in 4 days after receiving the mirror backing dimensions. The 0.05 mm spacers and optical window deserve explicit validation: a printed prototype can assess fit, but it will not establish molded optical clarity or clinical suitability. I would flag those features for the molder rather than assume a print proves their performance. Could you supply the mirror backing thickness/profile and intended resin so I can set the snap deflection and wall thickness appropriately? Gokay

Hi, I am a Mechanical Design Engineer and co-founder at Vutuk Design and Media. We specialize in medical/dental product CAD design, ergonomic housing development, DFM (Design for Manufacturing), and high-precision resin/SLA 3D printing prototyping. Designing a dental shield requires a balance between patient comfort, precise ergonomic fit, clear visibility/clearance for clinical tools, and biocompatible material selection. Using SolidWorks and Fusion 360, we can model a lightweight, contoured dental shield optimized for smooth sterilizability and cost-effective manufacturing—whether via rapid resin 3D printing or plastic injection molding. A few quick technical questions to align on your dental shield requirements: Do you have specific 3D jaw/facial scan data or dimensional target profiles, or will we be developing the shield profile around standard anatomical dimensions? What is your intended production material or manufacturing process (e.g., medical-grade autoclavability, clear biocompatible resin, or thermoformed/injection-molded polymer)? Would you like us to validate the design with physical SLA resin 3D prints to evaluate tactile fit and optical clarity before finalizing production files? Looking forward to helping you develop an ergonomic and functional dental shield prototype! Best regards, Ashraf Ali Shaikh

I can deliver a robust .STL and .STEP design for your dental mouth mirror shield, mirroring the efficient, injection-mold-ready approach I've used for similar disposable medical consumables where cost and manufacturability were paramount. My process will involve parametric modeling in SolidWorks to precisely capture your functional requirements. I'll focus on draft angles, wall thickness consistency, and radii optimization to ensure seamless injection molding without complex tooling. I'll then export .STL for 3D printing and .STEP for broader compatibility. What is the target tolerance for the snap-fit mechanism? Once we confirm the design parameters, I'm happy to schedule a quick call to walk through the proposed approach.
