About this service
Looking for a custom gear, gearbox, or reducer design that’s not only well-modeled in CAD but also engineered for performance? I can help.
I specialize in mechanical CAD design with a strong focus on power transmission systems. Every project goes beyond just 3D modeling — I also consider the engineering calculations that make your system work reliably.
What I provide:
📐 Gear ratio calculations based on your input/output speed and torque requirements
📦 Design optimization for available space (compact layouts, clearance checks, assembly fit)
🔩 Integration of off-the-shelf components (bearings, shafts, couplings, motors) or fully custom-designed parts
⚙️ Spur, helical, bevel, and worm gears, with proper tooth geometry and standards in mind
📝 2D technical drawings with tolerances and specifications for manufacturing
📂 3D models in multiple formats (STEP, IGES, STL, DWG, PDF, etc.)
🛠️ Manufacturability checks for CNC machining, injection molding, or 3D printing
Why choose me?
✅ Strong focus on functionality, not just pretty renders
✅ Calculations and checks to ensure your reducer works under load
✅ Flexible approach: cost-effective standard parts or fully custom assemblies
✅ Professional deliverables you can send directly to manufacturers
Whether you need a simple gear pair or a complete reduction gearbox assembly, I’ll make sure your design is accurate, optimized, and production-ready.
