I will create 3d cad models, technical drawings, and stl files
Muhammad Ahmad
About this gig
Is your product idea stuck at the sketch stage, uncertain if it can even be manufactured?
You dont need just a pretty 3D modelyou need a design that works on the factory floor. As a mechanical engineer specializing in SolidWorks and Design for Manufacturability (DfM), I bridge the gap between your vision and reality. I dont just draw parts; I engineer them to be cost-effective and production-ready, specifically optimized for injection molding, CNC machining, and sheet metal.
By choosing my services, you aren't just getting a model; you are de-risking your entire development cycle. I will ensure your product is easy to manufacture, saving you thousands in tooling modifications down the line.
Here is exactly what you will receive:
- Professional 3D CAD Models: Detailed assemblies and parts (SolidWorks/Source files included).
- DfM Analysis: A comprehensive review to eliminate expensive manufacturing pitfalls.
- Production-Ready 2D Drawings: Detailed technical drawings with dimensions, tolerances, and specifications for your machinist.
- Master File Formats: Clean STEP, STL, and native files ready for prototyping or mass production.

FAQ
Do you sign NDAs?
Yes. Every project is covered under a mutual NDA and IP agreement at no extra cost. Your idea stays yours — fully protected from day one.
What file formats do you deliver?
You receive STEP and IGES files compatible with any CAD software. SolidWorks native files are available as an add-on. PDFs of all technical drawings are included as standard.
What is included in your Mechanical Design service?
I provide end-to-end mechanical design including 3D CAD modeling, assemblies, manufacturing-ready drawings, and design support for production processes such as injection molding, CNC machining, and sheet metal fabrication.
Can you provide technical drawings for my factory?
Yes. I deliver fully dimensioned, manufacturing-ready technical drawings suitable for machining, fabrication, and production workflows. These include tolerances and annotations where required.
Can you design for injection molding?
Yes — and this is where most engineers get it wrong. I apply full DFM rules: draft angles, uniform wall thickness, gate placement, sink mark prevention, and parting line optimization. Your mold won't come back with expensive surprises.
Can you design for 3D printing?
Yes. I design for FDM, SLA, and SLS processes — optimized for your printer or a print service. Wall thickness, overhangs, support minimization, and layer orientation are all considered in the design.
Do you do ergonomic design and advanced surface modeling?
Yes. I work with G1 and G2 curvature continuity for ergonomic forms and aesthetic surfaces. If your product needs to feel right in someone's hand, that's built into the design process.
What does DFM actually mean for my project?
DFM means your design is engineered to be built, not just modeled. I review every design for process-specific constraints: tolerances, material behavior, tooling feasibility, and assembly logic. You won't hand a beautiful CAD file to a manufacturer and get told it can't be made.
Do you offer DFM engineering for new products?
Yes. I analyze your design for manufacturability and optimize it for processes such as injection molding, CNC machining, or sheet metal production to reduce cost and avoid production issues.
