Mechanical Clicker Keychain | Product Design, CAD Modeling & Design for Manufacturing
Simple products are often the most challenging to design well. This project explores the development of a compact mechanical clicker keychain that combines satisfying tactile feedback with a clean, durable, and manufacturing-friendly enclosure.
The objective was to create a pocket-sized everyday carry (EDC) accessory that feels premium, is comfortable to use repeatedly, and can be efficiently manufactured. The design process focused on balancing ergonomics, aesthetics, structural integrity, and ease of assembly while keeping the overall form compact enough for daily carry.
The product was developed as a fully parametric SolidWorks model, allowing every feature to be refined throughout the design process. I designed the enclosure around a mechanical switch assembly, incorporating internal alignment posts, snap-fit features, reinforcing ribs, optimized wall thicknesses, and smooth fillets to improve durability and manufacturability. The housing was also optimized for FDM 3D printing, reducing support material while maintaining strength and dimensional accuracy.
To communicate the complete engineering process, I created exploded assembly views, cutaway visualizations, internal component layouts, manufacturing optimization studies, and presentation-ready renders. These assets demonstrate not only the appearance of the product but also how it is assembled, functions internally, and can transition from prototype to production.
This project showcases my end-to-end product development workflow—from concept refinement and CAD engineering to design for manufacturing (DFM), rapid prototyping, and professional product visualization.

Nice work
One of our older concepts that still stands out to us is Sentra Wallet.
At the time, most crypto wallets leaned into dark themes and interfaces that felt built for experienced users. We wanted to explore a different direction. Something brighter, friendlier, and easier to navigate without losing the feeling of security or control.
The goal was simple: make managing digital assets feel approachable. We focused on clear information hierarchy, intuitive navigation, and a visual identity that didn't rely on the usual Web3 design trends.
Looking back, we'd definitely refine parts of it today, but the core idea remains the same. Great product design isn't about making crypto look more complex. It's about making it feel easier to use.
Going brighter and friendlier for a crypto wallet is still the harder design problem, most teams default to dark mode because it's easier to fake secure. What was the biggest pushback from users used to the darker wallet convention?
From CAD Assembly to Manufacturing-Ready Packaging Equipment
Every industrial machine starts with an engineering problem that needs a practical solution.
This project showcases the complete design and development of a 6-head automatic bottle capping machine, engineered in SolidWorks with a strong focus on manufacturability, reliability, and production efficiency. Rather than creating only a visual concept, the objective was to develop a machine that could realistically move from digital design into manufacturing.
The project covered the entire mechanical design process, beginning with the overall machine architecture and progressing through detailed component modeling, assembly design, engineering documentation, and final product visualization.
The machine was designed around a synchronized multi-head capping system capable of processing multiple bottles simultaneously while maintaining consistent torque, alignment, and repeatability. Every subsystem was carefully considered to ensure smooth operation, straightforward maintenance, and compatibility with industrial manufacturing methods.
Project Scope
• Industrial Product Design
• Mechanical Design
• 3D CAD Modeling
• Large Assembly Design
• Machine Frame Design
• Conveyor System Integration
• Servo Motor Integration
• Gearbox and Ball Screw Mechanisms
• Pneumatic System Layout
• Safety Guard Design
• HMI Control Panel Integration
• Technical Drawing Creation
• Manufacturing Documentation
• Product Visualization
Engineering Process
The project followed a structured engineering workflow that reflects how production equipment is developed for manufacturing.
The process included:
• Concept planning and machine architecture
• Mechanical system development
• Parametric part modeling
• Complete assembly creation in SolidWorks
• Motion and clearance validation
• Component organization using subassemblies
• Design for Manufacturing (DFM)
• Detailed engineering drawings with dimensions
• Bill of Materials (BOM)
• High-quality product rendering for presentation and documentation
Every component was modeled with manufacturing considerations in mind, allowing the design to remain clean, serviceable, and production-ready.
Design Highlights
The finished machine features:
✔ Six synchronized capping heads
✔ Stainless steel machine frame
✔ Integrated conveyor system
✔ Adjustable bottle guide rails
✔ Servo-driven lifting mechanism
✔ Ball screw positioning system
✔ Pneumatic capping assembly
✔ Touchscreen HMI control interface
✔ Protective guarding for operator safety
✔ Modular construction for easier maintenance
Deliverables
For this project, the final deliverables included:
• Fully detailed SolidWorks assembly
• Individual part files
• Manufacturing-ready CAD models
• Technical drawings
• Dimensioned fabrication drawings
• Assembly documentation
• Product renderings
• Production-ready engineering files
Industrial equipment design requires much more than creating accurate CAD models. Every decision, from component placement to assembly structure, affects manufacturing, maintenance, reliability, and long-term machine performance.
This project reflects my approach to industrial product design, combining engineering principles with practical manufacturing knowledge to produce designs that are not only visually clean but also functional and ready for production.
Whether you're developing a custom automation system, packaging equipment, production machinery, or a complex mechanical assembly, I can help transform your concept into detailed engineering documentation and manufacturing-ready CAD.
