Electrical Enclosure Design
Designed a weather-resistant electrical enclosure with a transparent poly-carbonate door for industrial applications. Utilized sheet metal fabrication (1.5mm stainless steel) to create a robust housing with IP65-rated seals, internal mounting points for PCB/component integration, and cable management slots. Delivered GD&T-compliant CAD models, DXF files for laser cutting, and assembly guides, reducing fabrication time by 20%.
About Me
SolidWorks & CAD/CAM Expert | 14+ Years | Sheet Metal & DFM Specialist Hi, I'm Abu Shahama Khan, founder of Arrant Engineering Solutions. I do two things: design manufacturing-ready mechanical products that don't fail on the shop floor, and build SolidWorks automation tools (C# add-ins, VBA macros) for engineering teams losing hours to repetitive CAD work. Track record: - Top 30 SolidWorks freelancer on Freelancer.com - 300+ clients across 50+ countries, 14+ years - 4.8/5 rating across 205+ reviews - 99% on-budget delivery, 87% on-time delivery - Preferred Freelancer, ASME Y14.5 GD&T Certified - Largest assembly delivered: 8,759 components Mechanical design work I've led (NDA-anonymized where required): - Multi-thousand-component sheet metal chassis for an acoustic recording studio (European client) — equation-driven parametric design that cut studio resize iterations from ~1 week to ~10 minutes - 20–30 m parametric maritime observation tower (German client) — DNV/ABS/IMO compliance, FEA validation coordinated through specialist third party - Multi-bay IoT parcel locker (USA) — lock-agnostic enclosure designed to accept UL 294-certified electronic lock modules from multiple manufacturers, IP54 ingress protection - IP65 outdoor display enclosure (Australia) — sheet metal + thermal management - FDA-regulated medical laser device (Canadian medical technology client, under NDA) — ISO 13485 design controls - Heavy industrial weldments and lifters, food-grade NSF/ANSI equipment, patent drawings for EU/UK/USA/China filings SolidWorks automation work: - Custom add-ins (C# / SolidWorks API) — drawing standard validators, BOM generators, custom property managers, EPDM workflow integrations - VBA macros for batch PDF/DXF/STEP exports, file rename utilities, and Pack-and-Go automation - Excel ↔ SolidWorks bridges for parameter tables and BOM round-tripping Stack: SolidWorks (advanced) • CATIA • NX • Creo • Inventor • AutoCAD - ANSYS (FEA/CFD) • KeyShot • C# / SolidWorks API • Visual Studio 2022 - 3D printing (FDM/SLS) Standards & compliance: ASME Y14.5 • ISO 9001 • ISO 13485 • FDA • UL/CE - DNV/ABS/IMO • IP54/IP65/IP67 • NSF/ANSI • DIN Why clients hire me: - Production-ready deliverables — manufacturing drawings, GD&T, flat patterns, BOMs that go straight to the shop floor - Manufacturing-aware design — I know what bend radii, weld preps, and tolerance schemes the fab line will accept - Direct communication with the engineer doing the work — no agency handoff chains - Comfort with regulated and complex projects — medical, maritime, industrial, IoT Based in India (IST). Working hours overlap with US-East 7–10 PM IST and EU 1–6 PM IST daily, with scheduled calls available for US-West and Australia. Send me your project — sketches, STEP files, or a description of the CAD bottleneck. I'll review and flag DFM or workflow risks upfront before you commit.
