Mechanical Design is a discipline of engineering that focuses on applying a combination of physical principles, mathematics, and materials science on the design, assembly, and maintenance of mechanical systems. The area often encompasses the development and analysis of both individual components and complete systems ranging from an entire car engine to smaller parts such as gears, levers, bearings, springs, hinges and other small mechanical parts. Mechanical Engineers use the knowledge and skills acquired to research, design, develop and test machines, engines and other types of tools for different industries. In essence, Mechanical Engineers create solutions that keep people and processes safe.

I’m looking for a mechanical designer who can take my concept for a CNC-machining production machine and turn it into a fully detailed design package. The end goal is a robust machine that will streamline manufacturing on our shop floor, so every decision—from frame geometry to drive selection—needs to prioritize rigidity, repeatability, and ease of maintenance. Here’s what I need from you: • 3D CAD models of the entire machine, including all motion components, guards, and service access points • Manufacturing-ready drawings (assemblies and individual parts) with tolerances and surface-finish notes suitable for CNC fabrication • A concise bill of materials that lists off-the-shelf parts alongside any custom components • Brief design ration...
I need a mechanical engineer who can take me from a rough idea to a fully documented, production-ready CNC machine. The emphasis is on manufacturing: the goal is to create a robust, accurate machine that will sit on my shop floor and turn raw stock into finished parts day in, day out. I am not looking for maintenance advice or just a new post-processor—I need the machine itself engineered. Here is what I expect: • Complete mechanical design in 3D CAD (SolidWorks, Inventor, or Fusion 360) including frame, linear motion components, spindle selection, drive system, guards and enclosure. • Detailed 2D drawings and an itemised BOM with off-the-shelf part numbers and suggested suppliers. • Strength, vibration and thermal checks to be sure the design will hold tolerance...

I manufacture professional dental loupes and now need a specialist to engineer the next-generation optical system for our lineup. The core brief is straightforward: produce a 3×–5× magnifier that delivers a crisp, wide field and can be dialed through several power steps for adjustable magnification. What I need from you • A full lens prescription and layout—prismatic or Keplerian, whichever meets the performance targets—modelled in Zemax, Code V, or an equivalent ray-tracing package. • Recommendations on glass types, coatings and lightweight housings so the finished loupe remains comfortable for all-day wear. An anti-reflective, easy-clean coating is strongly preferred. • Tolerance, MTF and illumination analyses that prove the design hold...
I’ve already sketched and modelled a sleek, pen-sized instrument that fuses four everyday essentials for medical-device reps: a fine-tip pen, a permanent marker, a rechargeable laser pointer, and a concealed, auto-retracting ceramic blade for opening cartons. Now I need to see it come to life in the form of one or two fully working prototypes that prove every feature actually functions. Functionality and quality are my top priorities. The prototypes have to write cleanly, shine a steady laser, and retract the blade the instant pressure is released. To make that viable all day, battery life and a convenient USB-C (or similarly compact) charging solution are non-negotiable. Safety is equally critical: the laser must include recessed button for activation, and the ceramic blade mechani...
I’m planning a statement-making indoor fountain that will stand over four feet tall and be fabricated entirely from metal, glass and stone and I need a precise CAD model to hand off to my fabricator. The project calls for a full 3D design with all the internal water-flow paths, pump housing, and hidden plumbing worked out so production is straightforward. My main priorities are: • Accurate dimensional drawings and a clean, editable 3D file (STEP or similar) that shows every component, including joints, fasteners, and the water reservoir. • Simple exploded views or section cuts so my fabricator can see how each layer assembles and where the pump and tubing sit. • A quick rendering or two that conveys the final look for stakeholder sign-off. When you reach out, ple...
I need a detail-oriented drafter who can take my mechanical part concepts and translate them into clean, production-ready 2D drawings in AutoCAD. I’ll provide the reference sketches and key dimensions; you turn them into properly layered DWG files with clear annotations that a machinist can follow without a second guess. Deliverables • Native AutoCAD (.dwg) files for each part • Matching PDF prints for quick review and shop use • All critical dimensions, tolerances, and notes visible and consistent across views Acceptance criteria The drawings open error-free in AutoCAD 2021+, line weights and layers are logically organised, and dimensions match the supplied measurements within standard drafting tolerance. If you have a portfolio of similar mechanical part d...
I need a purpose-built wall-mount bracket arm that can telescope out between 30 cm and 60 cm while keeping a square VESA interface (75 mm and 100 mm patterns) on both ends. Aluminum is required for the entire structural portion so the finished piece stays light yet sturdy, and it must safely hold displays or light equipment up to 10 kg without noticeable sag or play. The task covers the full mechanical design and manufacturing preparation. A clean industrial look, concealed cable channel, and smooth, tool-free extension mechanism are highly preferred, but function and strength remain top priority. Please base the design on standard aluminum profiles or custom-machined parts—whichever gives the best mix of rigidity, weight, and cost. Deliverables • 3D CAD model (STEP or SolidWo...

I’m developing a hands-on robot that helps learners grasp coding and programming concepts, and I need a mechanical designer who can take the idea from sketch to production-ready CAD using SolidWorks. The goal is an engaging educational robot—think classroom-safe, modular, and easy to assemble—that physically demonstrates code in action (moving, gripping, lighting up, etc.). I already know what the electronics will do; what I’m missing is the full mechanical package: chassis, actuators and sensor mounts, snap-fit or screw-together panels, wire-routing, and anything else that turns the electronics into a robust teaching tool. Key expectations • Work entirely in SolidWorks, supplying all native files alongside STEP/IGES exports • Develop the full 3-D mo...
I have a single hand‑drawn schematic of custom distillation equipment that needs to be converted into a clean, accurate, professional mechanical drawing suitable for direct submission to a fabricator. All dimensions on the sketch have already been verified. But there might be questions that the Freelancer may have in order to do this properly. Your task is not to redesign, interpret, or modify the geometry — only to faithfully transfer the drawing into proper drafting format. I also have multiple photos of the real equipment, and additional measurements can be taken on site upon request. If you need a specific angle, dimension, or detail to ensure accuracy, I can provide it quickly.

(Like he worked in any major airlines company , boeing or airbus) If you don't have an experience , please dont waste my time because I will ask you about a well known component (Don't ask Chat gpt because I know their answers :) I will ask for hand sketch before I make any commitment
I’m rebuilding the optics in my light-measurement device. Right now the module relies on two lenses, a circular diffuser plate, and an aperture to guide visible light from a 30 mm entrance circle down to the 5 mm active area of the detector. It works, but the cost of the double-lens stack is no longer acceptable. Your mission is to engineer a new light path that achieves the same 30 mm-to-5 mm concentration using just one readily available, low-cost catalogue lens. Please analyse the ray geometry, calculate transmission and spot size, and confirm that we stay within the detector’s field of view while avoiding vignetting or excessive aberrations. If a minimal diffuser or baffle is still required, specify it, but the core goal is a single-element solution. I will need: • ...
